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.

    $\begingroup$ When this content is flagged, and people are doing so, it ends up in all the moderators' special mod inbox. So we are definitely aware of it! The 'why exactly now?' is a hard one. Who knows? All the LLMs going online makes it easier for people to use them to try their hand, for reasons best known to themselves. As for what is being done, we are doing what we have always done with accounts that are made just to post stuff that's not wanted :-) But as Scott mentioned: flag flag flag. Flagging such content as spam triggers automated tools to do their work. $\endgroup$

  • $\begingroup$ @DavidRoberts At the risk of derailing: is there a queue where one can see "all new answers"? I tend to rely on checking the front page but this only shows questions with recent activity, and some of this is editing $\endgroup$

    $\begingroup$ @YemonChoi mathoverflow.net/questions?tab=Newest works, I think. You have to go through the 'questions' link in the menu on the left (under the hamburger lines, for me) and then you can pick 'newest', 'active', 'unanswered', or even a custom filter for instance for just the newest with the tags you care about. $\endgroup$

Once in a while, people decide to post strange things here. I would recommend not giving them the pleasure of a response. The best thing to do is flag and ignore.

    $\begingroup$ I don't think this answers any of the questions: why now, are mods aware, what is being done? $\endgroup$

    $\begingroup$ @BenMcKay Yes we are aware. We are cleaning up as it comes to our attention, and this includes things that increase the friction to continue posting such questions/answers from someone who does so. How else would you propose we deal with it? $\endgroup$

  • $\begingroup$ @DavidRoberts: You can probably do more. For example, you can ban users who post obvious garbage, and also ban users who support the garbage (e.g. upvoting). Why is this important? If garbage has no upvotes, it is more easily cleaned up. The upvoters of garbage are almost always garbage generators themselves. $\endgroup$
