A potential federation with Threads (should Thread decide to implement it) would overwhelm Lemmy/Mbin/Piefed with millions of users (compared to the 40k monthly current active users), transforming those platforms into a threaded version of Facebook
I'm not sure what's the moderation philosophy that's welcoming him to these instances. It's possible that because he hasn't caused a problem yet on the new accounts, there's no harm done, but I would be saddened and surprised if the more up-to-speed places were as lenient with him as LW was.
He's still around, he showed up in my All feed the other day, on lemm.ee now IIRC
He's got an account on sh.itjust.works, too.
