ArXiv to ban authors for a year over unchecked AI-slop preprints

ArXiv announced a new policy banning authors for a year if their papers show 'incontrovertible evidence' of unchecked LLM use — hallucinated references, leftover model meta-comments, fabricated results. The move targets a surge of AI-slop preprints flooding the platform. r/MachineLearning split sharply: a 594-upvote thread supported it, while a 526-upvote companion thread found the backlash 'genuinely perplexing.'
