Dietterich also notes that all authors of a manuscript are responsible for its content. So, if they carelessly submit material generated by an AI that violates these guidelines—Dietterich cites “inappropriate language, plagiarized content, biased content, errors, mistakes, incorrect references, or misleading content”—then they’re responsible, not the AI. Should violations be discovered, all of the manuscript’s listed authors will now receive a one-year submission ban, and any future manuscripts will only be accepted after they’ve been through peer review by a journal.

But also... More worrisome :

The unfortunate problem is that, like most other things, the system can be gamed—people could submit flawed content that lists people as authors who have never been involved. Fortunately, its moderation system includes an appeal process.

Go ahead, get your science nemesis on the arXiv black list~~
