arXiv was built over a good faith assumption, where a long paper meant at least the author had put some effort behind, and a every idea deserved attention. AI generated text breaks that assumption, and anybody uploading it is not acting in good faith.
And it's a unequal arms race, in which generating endless slop is way cheaper than storing it, because slop generators are subsidised (by operating at a loss) but arXiv has to pay the full price for their hosting.
