Anyone else seeing a sudden uptick in bot followers?

Has anyone noticed a sudden surge in bot followers? I used to get one suspicious looking follower every week or two, but in the last 24 hours or so I've gotten almost 100.

Most are only about a week old, and have a dozen or so reposts but 0 posts of their own. The profile images are typically either a female headshot that looks like a stock-photo or AI generated, or a poorly cropped diagram or webpage header image.
