Right now the site is being flooded with posts from new users, with pseudonymous names, who use a mixture of obvious AI-generated nonsense mathematics and weird sentences (sometimes borderline offensive?) about things that have nothing at all to do with math (which are I would guess actually written by humans and not AI).

Why is this happening right now? Are the moderators aware of the situation? What is being done to address it?

If this continues, the site will become increasingly non-functional.
