ArXiv, the world's largest preprint server, announced in May 2026 that researchers who submit papers containing obvious AI-generated content will face a one-year ban followed by permanent restrictions requiring peer-review acceptance before future submissions. The policy arrives as rejection rates have quadrupled from 2.5% to 10% and an estimated one-fifth of computer science papers now contain detectable AI text—raising urgent questions about enforcement accuracy, equity for non-English-speaking researchers, and whether bans will fragment the scientific publishing ecosystem.
