Sort of unrelated but a recent interaction with LawTwitter pretty much confirms to me they have some kind of group chat they use to dogpile people.

These are in response to a thread about Chris Avellone from last year, and when I jumped into it they all immediately went back into chain-replying and swarming everyone who replied to them negatively while talking about how the thread is so old and that it isn't important or relevant anymore. The reply to the houe picture literally got more likes than the OP post that started the whole thing.
I legit don't know how else they could all be seeing these tweets of an 18 month old thread beyond some sort of group organization while gassing them up in such giant droves. It's pretty much artificial engagement at that point.
