Also check your LaTeX comments, Arxiv makes those publicly visible!!!

I'm a screen reader user and usually read papers as raw TeX. I've seen everything: slurs, demeaning comments towards reviewers and professors, admissions of fraud, instructions to coauthors to commit further fraud before paper submission to mask the earlier fraud... it's all there. There's far less of it than I would think, definitely <1% of papers, but it's there.

I think it would be useful to run an LLM anti-fraud pass on the TeX source of all new arxiv papers. It wouldn't catch everything, but it would catch some of the dumbest fraudsters.

On the positive side, you can also find stronger claims that didn't survive review, additional explanations that didn't make the cut due to the conference's page limit, as well as experimental results that the authors felt weren't really worth including. Those need to be approached with an abundance of caution, but are genuinely useful sometimes.
