PubPeer-Flagged Fraud in Biomedical Research Papers

😈 **Devil's Advocate Critique:** Additional retractions likely stem from honest figure errors or poor practices rather than intentional fraud, as many PubPeer flags result in corrections not misconduct findings; platform's anonymity facilitates unverified accusations and harassment claims, as in prior lawsuits, without accuser accountability.
