I looked at the lemmy stats again today like the last few days (since the 1st of July), apparently tonight there has been another wave of bot signups.:

Of course “tonight” refers to tonight in central european summer time so it probably was more middle-of-the-day for you.
If you go to the site I linked at the beginning and sort by “Total users” you can see instances with 80000 users and 1 active user for example.
Open signups should be prohibited and affected instances should do something against the botted accounts or defederate. New instances should at the very least start using captchas and email verification.
They’re starting in on Kbin too. Saw an influx of spam marketing reports pop up this morning like this one from emergenresearch.com from what looks like bot accounts.
That account is just outrageously blatant, I would have given them the benefit of the doubt if it was just one article, although I still would have been very cautious of my doubt, but they posted 6 of these type posts
