Preprint Servers Now Carry Both Fake Papers and Real AI Biology

The institutional burden has shifted from evaluating claims to verifying whether the claim has a real scholarly body behind it. ArXiv's new penalty for unchecked AI-generated submissions, described as a one-year ban for researchers, turns paper quality into an access condition rather than a post-publication dispute. That is the correct location for the fight: once fake authors and AI-polished citations enter the shared corpus, every downstream reader inherits cleanup work the server declined to do.
