At PLOS ONE alone, of 18{,}329 editors who have ever accepted a submission, a Poisson-binomial enrichment test flags 45, a mere 0.25\%, who together handled 1.3\% of the journal's 276{,}956 articles but sit behind 30.2\% of its 702 retractions. More than half of them, 25 of 45, also authored papers that PLOS ONE retracted. A cluster of them spanning four countries sent most of their submissions to each other rather than to the journal's other 18{,}284 editors. The same signature, self-referential acceptance, batched retractions, and a shared trail of duplicated images, reappears at Hindawi and across IEEE conference proceedings. This Field Note walks through exactly how the authors caught it, why a coordinated ring is a fundamentally harder catch than a single fabricated paper, and what the exercise implies, and does not imply, about trusting the other 99.75\% of editors doing the job honestly. All illustrative arithmetic beyond the paper's own reported numbers is clearly marked as the club's own; we ran no experiment and analyzed no new data of our own. \end{abstract} %============================================================================ \section{Forty-Five Names on Two Spreadsheets} Two spreadsheets did it. Not a whistleblower, not a leaked internal email, not a confession extracted under pressure. Two ordinary bibliographic exports: one listing which handling editor accepted which manuscript at a journal, the other listing which of those manuscripts were later retracted or drew a comment on PubPeer. Merge them. Run a statistical test on every editor who has ever worked there. See who comes out anomalous. At PLOS ONE, which is unusual among large journals in publicly naming the editor who handled each accepted paper, that test flags forty-five people \cite{richardson2025}. Forty-five out of 18{,}329 editors who have accepted at least one article since the journal launched in 2006, a group so small it is 0.25\% of everyone who has ever done the job. Between them they have handled 1.3\% of the journal's 276{,}956 published articles. And they account for 30.2\% of everything the journal has ever had to retract. That is the headline of a paper by Reese Richardson, Spencer Hong, Jennifer Byrne, Thomas Stoeger, and Lu\'is Amaral, published in the \textit{Proceedings of the National Academy of Sciences} in August 2025, titled ``The entities enabling scientific fraud at scale are large, resilient, and growing rapidly'' \cite{richardson2025}. One of the authors, Amaral, is himself a longtime PLOS ONE editor, which is part of why the paper reads less like an outside accusation and more like an institution auditing itself. What follows is our attempt to understand the machinery behind that number. How do you catch forty-five people doing this without a confession? Why is a network of colluding editors so much harder to catch than one person faking a gel image? And once caught, what does it change about trusting the review process the rest of us rely on? %============================================================================ \section{Defection, Not Villainy} The paper's own framing is worth taking seriously before the numbers. Richardson and colleagues borrow a term from game theory: \emph{defection} \cite{richardson2025}. Treat the scientific enterprise as a public-goods game in which everyone benefits from a shared pool of trustworthy knowledge and is supposed to contribute genuine work to it. A defector takes the benefits without contributing genuine knowledge. Historically defection was assumed to be rare and individual: one person under career pressure fabricates one dataset. The paper's taxonomy has three moving parts, and they are not the same thing. \emph{Paper mills} mass-produce fake or low-quality manuscripts for sale. \emph{Brokers} connect that supply to journals willing to publish it, sometimes by paying editors, sometimes by embedding themselves as editors. \emph{Predatory or hijacked journals} are the venues, sometimes legitimate journals a broker has captured outright, that skip the quality control a journal is supposed to provide. None of the three alone needs a network of forty-five people. What needs the network is doing all three at once, repeatedly, at a scale bigger than any single fabricator could manage alone. %============================================================================ \section{How You Catch an Editor Doing This} \label{sec:method} PLOS ONE has published 276{,}956 articles since 2006. Of those, 702 have been retracted and 2{,}241 have drawn a comment on PubPeer \cite{richardson2025}. Neither number is evenly spread across the journal's history or its 18{,}329 editors. For every editor, for every year active, the authors counted how many manuscripts that editor accepted were \emph{eventually} retracted, and separately how many eventually drew a PubPeer comment, then asked: given the journal-wide, time-varying background rate, is this editor's count higher than chance would produce? The tool is a Poisson binomial test, run editor by editor, with the false discovery rate held at 0.05 across all 18{,}329 simultaneous tests \cite{richardson2025} --- the same multiple-testing correction problem as testing thousands of genes at once, applied here to thousands of editors. They ran the test three ways: eventual retraction, eventual PubPeer comment, and unusually short turnaround (30 days or fewer between submission and acceptance), a hallmark some regard as paper-mill-adjacent processing \cite{richardson2025}. Retraction anomalies flagged 22 editors; PubPeer anomalies flagged 33; short-turnaround anomalies flagged 88. But when the authors checked whether \emph{authors} were disproportionately routed to those flagged editors, the numbers inverted: 21 authors for the retraction-flagged group, 18 for PubPeer, and only 7 for short turnaround. A footnote from Amaral explains part of why: PLOS ONE itself once actively encouraged fast turnaround as policy, later deprioritized, so some flagged editors were simply following journal guidance \cite{richardson2025}. The authors' own data show their weakest signal being weak for a documented, non-nefarious reason. \begin{figure}[htbp] \centering \begin{tikzpicture} \begin{axis}[ width=12.5cm, height=7cm, ybar, bar width=16pt, ymin=0, ymax=100, symbolic x coords={retraction anomaly, PubPeer anomaly, short turnaround}, xtick=data, x tick label style={font=\small}, ylabel={people flagged}, ymajorgrids=true, grid style={dashed, gray!30}, legend style={font=\scriptsize, at={(0.02,0.97)}, anchor=north west} ] \addplot[fill=ledger, draw=ledger] coordinates { (retraction anomaly,22) (PubPeer anomaly,33) (short turnaround,88) }; \addlegendentry{editors flagged} \addplot[fill=millgold, draw=millgold] coordinates { (retraction anomaly,21) (PubPeer anomaly,18) (short turnaround,7) }; \addlegendentry{authors disproportionately routed to them} \end{axis} \end{tikzpicture} \caption{Three anomaly signals across all 18{,}329 PLOS ONE editors, FDR held at 0.05. Short turnaround flags the most editors (88) but the fewest complicit authors (7), consistent with the paper's footnote that PLOS ONE briefly encouraged fast turnaround as policy. Data: \cite{richardson2025}.} \label{fig:signals} \end{figure} %============================================================================ \section{The Ones Who Send Work to Each Other} The 22, 33, and 88 above overlap and don't capture everyone: an editor can also be flagged indirectly, by having their own submissions disproportionately handled by \emph{other} flagged editors. Combine every direct and indirect route and the total comes to 45 PLOS ONE editors \cite{richardson2025}. Here is the club's own arithmetic on top of that. If retractions were distributed in proportion to workload, 45 editors responsible for 1.3\% of PLOS ONE's articles should be responsible for about 1.3\% of its 702 retractions: roughly 9. They are instead responsible for 30.2\%, or about 212. Dividing 212 by 9 gives a group producing retractions at more than \textbf{23 times} the rate their workload share would predict. That ratio is ours; the paper reports the two percentages, we divided them. More than half, 25 of the 45, also personally authored articles that PLOS ONE went on to retract \cite{richardson2025} --- the same people appear on both sides of review. Mapping who sent submissions to whom, the authors found a densely connected cluster of editors serving 2020--2023, based across four countries, who sent most of their own submissions to each other rather than to the journal's other 18{,}284 editors. More than half of the articles this cluster accepted were later retracted, with near-identical retraction notices: \begin{quote} \itshape ``One of a series of submissions for which we have concerns about authorship, competing interests, and peer review.'' \end{quote} \hfill --- as reported in \cite{richardson2025}, citing PLOS ONE editorial notices The paper flags an honest complication worth repeating: editor assignment at PLOS ONE is nominally close to random, but authors may recommend an editor, so an author landing with a preferred editor ``is not unlikely'' on its own \cite{richardson2025}. Some of what looks like editor-side self-dealing could in principle be author-side targeting of accommodating editors; the statistical signature does not fully distinguish the two, and the paper does not pretend it does. \begin{figure}[htbp] \centering \begin{tikzpicture} \begin{axis}[ width=12.5cm, height=7cm, ybar, bar width=22pt, ymin=0, ymax=35, symbolic x coords={share of editors, share of articles, share of retractions}, xtick=data, x tick label style={font=\small}, ylabel={share attributable to the 45 flagged editors (\%)}, ymajorgrids=true, grid style={dashed, gray!30} ] \addplot[fill=ledger, draw=ledger] coordinates { (share of editors,0.25) (share of articles,1.3) }; \addplot[fill=flagred, draw=flagred] coordinates { (share of retractions,30.2) }; \end{axis} \end{tikzpicture} \caption{A quarter of one percent of PLOS ONE's editors, handling 1.3\% of its articles, accounts for 30.2\% of its retractions --- about 23$\times$ their proportional share, by the club's own division of the paper's two percentages. Data: \cite{richardson2025}.} \label{fig:disproportion} \end{figure} %============================================================================ \section{Same Story at Other Journals, and in Conference Halls} Hindawi, the other publisher that discloses handling editors, offers an independent test of whether the pattern generalizes. Restricting to the ten Hindawi journals with the most retractions and PubPeer comments, the same procedure flags 53 editors for anomalous retraction rates, 52 for anomalous PubPeer rates, and 96 for anomalous fast-tracking, with six, four, and seven of those respectively flagged at more than one journal simultaneously \cite{richardson2025}. The method also extends to a venue with no single ``editor'': IEEE conference proceedings. Treating each organizing committee as equivalent to an editor, the authors examined 2{,}294{,}067 articles across 19{,}969 IEEE conferences since 2003. Forty-five conferences held 2009--2011 had more than 10\% of their published articles eventually retracted, producing a visible spike in the retraction record around those years \cite{richardson2025}. The full test flags 84 conferences for retraction anomalies, 158 for PubPeer anomalies, and 183 for anomalously frequent ``tortured phrases,'' the garbled synonym-substitutions typical of paraphrasing software used to evade plagiarism detection. At least seven multi-year IEEE conference series were flagged for tortured-phrase anomalies in \emph{every single year} they were held \cite{richardson2025}. %============================================================================ \section{A Second Fingerprint, Left in the Images} Editorial handling records are one line of evidence. The paper builds a second, independent one from duplicated images. Starting from PubPeer reports of image duplication, the authors constructed a network of 2{,}213 articles (nodes) connected by 4{,}188 duplicate-image observations (edges), splitting into 20 connected components, the largest holding 622 articles \cite{richardson2025}. Using stochastic block modeling to find internal structure, two results stand out. First, articles inside a given module are not randomly distributed across publication year or publisher; a Shannon-entropy test rejects that null for essentially every module with enough data to test \cite{richardson2025} --- consistent with a broker placing a batch of manuscripts in one venue within a tight window, rather than independent authors reusing their own old figures. Second, despite hard visual evidence that its underlying data cannot be what it claims, only 34.1\% of this network has actually been retracted \cite{richardson2025}. Two-thirds of a network built entirely of provably duplicated images sits uncorrected in the scientific record. \begin{figure}[htbp] \centering \begin{tikzpicture} \draw[flagred, line width=1.4pt] (0,0) -- (0:1.5) arc[start angle=0, end angle=-122.76, radius=1.5] -- cycle; \fill[flagred, opacity=0.85] (0,0) -- (0:1.5) arc[start angle=0, end angle=-122.76, radius=1.5] -- cycle; \draw[ledger, line width=1.4pt] (0,0) circle (1.5); \node[font=\bfseries] at (0,0.3) {622}; \node[font=\small] at (0,0.02) {articles}; \node[font=\small, anchor=west] at (1.7,-1.0) {\textcolor{flagred}{34.1\% retracted}}; \node[font=\small\itshape, anchor=north] at (0,-2.0) {largest connected component}; \node[font=\small, anchor=north] at (0,-2.9) {network total: 2{,}213 articles \textbullet\ 4{,}188 duplicate-image edges \textbullet\ 20 components}; \end{tikzpicture} \caption{The largest component of the image-duplication network, wedge shaded to the retracted fraction, mirroring the paper's own Figure 2C convention. Data: \cite{richardson2025}.} \label{fig:network} \end{figure} %============================================================================ \section{Why Not Just Check Who Cites Whom?} A natural guess about how you'd catch a cartel of cooperating editors is worth confronting directly, because it is not what this paper did. If a group of editors and authors were cooperating, wouldn't they also cite each other, inflating citation counts and impact factors the way documented citation cartels do elsewhere? Coordinated editorial action toward exactly that goal is real and separately studied: a 2022 \textit{Research Policy} paper examined how institutions and journals game citation-based rankings \cite{siler2022}, and a 2024 \textit{Scientific Reports} paper mapped fabricated co-authorship networks used to sell authorship slots \cite{porter2024}. But that is not the fingerprint Richardson and colleagues pulled up. Nowhere in the PLOS ONE, Hindawi, or IEEE analyses does a citation network appear. The signal was who \emph{accepted} whose manuscript and who \emph{reused} whose image, not who \emph{cited} whose paper. That distinction changes what a ring has to do to stay invisible. A citation cartel has to cite, leaving tracks exactly where bibliometricians already look. A network that fast-tracks and rubber-stamps each other's submissions needs no cross-citing at all --- the papers can sit in entirely unrelated subfields and never once reference one another. An audit that only ever examined citation graphs, however sophisticated, would have sailed straight past this one. %============================================================================ \section{The Business That Follows the Deindexing List Around} The paper's clearest evidence for an organized broker is a named case study: ARDA, whose website as of June 2024 advertised ``Conferences and Meetings,'' ``Journal Publication,'' and ``Thesis/Article Writing,'' and claimed involvement in ``4{,}565+ publications'' \cite{richardson2025}. Since January 2018, ARDA has listed 188 unique journals as guaranteed publication venues, growing from 14 journals in January 2018 to 86 by March 2024 --- roughly 34\% compound annual growth in portfolio size over six years, by the club's own arithmetic on those two endpoints. Of the full list, 106 (56.4\%) were Scopus-indexed, 51 (27.1\%) Web-of-Science-indexed, 29 (15.5\%) both, and 2 (1.1\%) MEDLINE-indexed; 17 (9.0\%) are suspected ``hijacked journals,'' formerly legitimate titles a paper mill has captured outright \cite{richardson2025}. A journal ARDA listed in 2020 that was Scopus-indexed at the time had a 33.3\% chance (13 of 39) of later being deindexed, versus a 0.5\% baseline (147 of 27{,}197) for Scopus-indexed journals actively publishing in 2020 generally, a difference the paper confirms with a two-tailed test ($P < 0.0001$) \cite{richardson2025}. Dividing those percentages, as the club did, puts an ARDA-listed journal at roughly \textbf{66 times} the deindexing risk of an ordinary journal. When a batch of journals was deindexed in 2020--21, ARDA dropped them from its site by May 2021 and replaced them with new titles \cite{richardson2025}. For five ARDA-listed journals inspected in detail, 34.0\% to 98.7\% of published articles fell entirely outside the journal's stated scope. \begin{figure}[htbp] \centering \begin{tikzpicture} \begin{axis}[ width=6cm, height=6cm, ybar, bar width=26pt, ymin=0, ymax=100, symbolic x coords={Jan 2018, Mar 2024}, xtick=data, x tick label style={font=\scriptsize}, ylabel={journals listed by ARDA}, ymajorgrids=true, grid style={dashed, gray!30} ] \addplot[fill=ledger, draw=ledger] coordinates {(Jan 2018,14) (Mar 2024,86)}; \end{axis} \end{tikzpicture} \hspace{0.4cm} \begin{tikzpicture} \begin{axis}[ width=6cm, height=6cm, ybar, bar width=26pt, ymin=0, ymax=40, symbolic x coords={baseline 2020, ARDA-listed 2020}, xtick=data, x tick label style={font=\scriptsize, rotate=12, anchor=east}, ylabel={\% later deindexed by Scopus}, ymajorgrids=true, grid style={dashed, gray!30} ] \addplot[fill=ledger, draw=ledger] coordinates {(baseline 2020,0.5)}; \addplot[fill=flagred, draw=flagred] coordinates {(ARDA-listed 2020,33.3)}; \end{axis} \end{tikzpicture} \caption{Left: ARDA's portfolio grew sixfold in six years.

Data: \cite{richardson2025}.} \label{fig:arda} \end{figure} %============================================================================ \section{Some Fields Are Simply Better Targets} Restricting to six closely related, similarly sized RNA biology subfields with comparable growth since roughly 2000, the authors tracked annual publication counts alongside annual errata and retraction rates from 2002 to 2022 \cite{richardson2025}. Errata sit in a narrow band of 1.5\% to 2.5\% across all six subfields; the literature in each is revisited for ordinary reasons at roughly the same rate. Retraction rates do not share that consistency. CRISPR-Cas9 sits near 0.1\%. Transfer-RNA-and-cancer studies peak near 1\%. Circular RNA studies peak near 2.5\%. Both microRNA-and-cancer and long non-coding RNA studies peak near 4\%, and for individual journals in those two subfields the rate exceeds 10\% \cite{richardson2025}. Because the errata baseline stays flat while retraction rates swing roughly 40-fold across subfields studied with the same tools over the same period, the authors argue the gap reads as targeting rather than a maturity artifact. \begin{figure}[htbp] \centering \begin{tikzpicture} \begin{axis}[ width=13cm, height=7cm, ybar, bar width=20pt, ymin=0, ymax=5, symbolic x coords={CRISPR-Cas9, tRNA \& cancer, circular RNAs, miRNA \& cancer, lncRNAs}, xtick=data, x tick label style={font=\scriptsize, rotate=12, anchor=east}, ylabel={peak retraction rate (\%)}, ymajorgrids=true, grid style={dashed, gray!30} ] \addplot[fill=ledger, draw=ledger] coordinates { (CRISPR-Cas9,0.1) (tRNA \& cancer,1.0) (circular RNAs,2.5) (miRNA \& cancer,4.0) (lncRNAs,4.0) }; \draw[millgold, dashed, line width=1pt] (axis cs:CRISPR-Cas9,1.5) -- (axis cs:lncRNAs,1.5) node[pos=0.5,above,font=\scriptsize,millgold]{errata band 1.5--2.5\%}; \end{axis} \end{tikzpicture} \caption{Retraction rate swings roughly 40-fold across six matched RNA biology subfields while the errata rate stays flat. Data: \cite{richardson2025}.} \label{fig:rna} \end{figure} %============================================================================ \section{The Arithmetic of Outrunning Everyone Chasing It} The paper's closing empirical argument is about speed. Comparing four annually growing quantities, the authors report doubling times of 15.0 years for total global scientific output, 3.6 years for PubPeer-commented articles, 3.3 years for retracted articles, and 1.5 years for suspected paper-mill products \cite{richardson2025}. Doubling times are awkward to compare by eye, so here is the club's own conversion: a doubling time $T$ corresponds to a continuous annual growth rate $r = \ln(2)/T$. Applied to the paper's four numbers: \begin{table}[htbp] \centering \begin{tabular}{lrr} \toprule \textbf{Quantity} & \textbf{Doubling time (paper)} & \textbf{Annual rate (club, $\ln2/T$)} \\ \midrule Total global publications & 15.0 y & 4.6\% \\ PubPeer-commented articles & 3.6 y & 19.3\% \\ Retracted articles & 3.3 y & 21.0\% \\ Suspected paper-mill products & 1.5 y & 46.2\% \\ \bottomrule \end{tabular} \caption{Doubling times: \cite{richardson2025}. Growth-rate column: club arithmetic.} \label{tab:growth} \end{table} Divide the fastest rate by the slowest and the fraud economy, as the paper's own trend lines describe it, is growing at almost exactly \textbf{ten times} the rate of legitimate science itself. Web of Science and Scopus each deindex on the order of a hundred journals a year, tenfold smaller than the number of journals currently publishing suspected paper-mill products \cite{richardson2025}. Of 29{,}956 suspected paper-mill products with a matching OpenAlex record, only 8{,}589 (28.7\%) have actually been retracted; extrapolating current trends, the authors project only around 25\% will ever be retracted and only around 10\% will ever end up in a deindexed journal \cite{richardson2025}. On the paper's own projection, roughly three out of four papers already identifiable as probable paper-mill products today will sit uncorrected in the record indefinitely. %============================================================================ \section{Why This Beats the Immune System Built for Lone Fabricators} A lone fabricator concentrates risk: one person, one paper, one implausible dataset. The signal is small in scope but large in magnitude, exactly what post-publication review sites like PubPeer are built to catch. A coordinated network does the opposite: it distributes risk unevenly, by design or by accident. Of the 45 flagged PLOS ONE editors, only 22 carried an individually anomalous retraction rate on their own record --- a needle so fine, out of 18{,}329 editors, that finding it required a purpose-built statistical test run simultaneously on everyone who has ever done the job, with a false-discovery correction to stop the multiple-testing problem itself from manufacturing false positives. The other 23 needed no anomalous personal record at all: they were caught only because they routed submissions to editors who were already flagged, a second, independent signal unrelated to any one person's own numbers looking alarming. Catching one bad paper takes a reader with good instincts. Catching this took a research team, a full retraction database, PubPeer's comment archive, and a statistical method sophisticated enough to separate a real coordinated signal from eighteen thousand editors' worth of ordinary noise --- and even then, the network described operated for at least three years, 2020 to 2023, before this analysis surfaced it. %============================================================================ \section{What This Should, and Should Not, Change About Trusting Peer Review} It would be easy to flatten this into ``peer review is broken.'' The paper resists that reading. Forty-five editors is 0.25\% of everyone who has done the job at PLOS ONE; the other 99.75\% show no statistical anomaly at all. The finding is not that editors, as a class, cannot be trusted. It is that an accountability system built around the assumption that fraud is rare and individual has little capacity against fraud that is organized and cooperative. The authors' own discussion is structural rather than moralistic. Journal editors ``have been offered substantial payments for rapid publication of selected manuscripts,'' and ``coordinated editorial action has been implicated in efforts to increase the impact factor of journals'' \cite{richardson2025}, citing among other work the impact-factor gaming literature above \cite{siler2022}. The people currently doing the work of finding this are, in the authors' words, ``courageous but isolated individuals,'' some ``accused of vigilantism and dismissed,'' others ``threatened with legal action'' \cite{richardson2025}. Their recommendation: separate detection, investigation, and sanctioning, and remove each from the hands of parties with a conflict of interest in the outcome. A coda in the discussion deserves attention. Both symbolic ``machine scientists'' and large language models are increasingly used to summarize the literature, and none can currently distinguish a real paper from a fraudulent one \cite{richardson2025}. Every fraudulent paper this network produced, and every one still uncaught, becomes an input to systems built on the premise that the literature they read is trustworthy --- and that compromised fraction is, by the paper's own numbers, the fastest-growing fraction there is. %============================================================================ \section{What the Authors Themselves Flag as Limits} The paper's limitations section is direct. The analysis can only find fraud that has already left a trace in the corpora available, and the expert consensus it cites holds that the large majority of paper-mill products have not yet been detected at all \cite{richardson2025}. Case studies such as ARDA and the RNA biology subfields focus on particular businesses or disciplines that may not generalize. And changes over time in how much attention watchdogs pay to different fields could themselves produce trends that look like growth in fraud without being growth in fraud, a possibility the authors say they cannot fully rule out. We end where the authors end their own discussion: not with a verdict that the system has failed, but with an argument that detecting fraud at this scale cannot keep being the work of isolated volunteers. It needs resources commensurate with a fraud economy growing, by the paper's own trend lines and the club's own arithmetic on them, about ten times faster than the science it hides inside of. %============================================================================ \begin{thebibliography}{9} \bibitem{richardson2025} Richardson, R.~A.~K., Hong, S.~S., Byrne, J.~A., Stoeger, T. \& Amaral, L.~A.~N.
