I think this comment chain is going in a circle while everyone actually agrees with the underlying point.
I cannot see anything bad here. Blocking an actively malicious actor should be the norm.
It might be true that they aren't ACTIVELY being malicious currently. It's also true that they have a horrible history, and they will likely be actively malicious in the future.
(I say 'might' because I seem to recall them being malicious towards the fediverse with secret meetings with admins, but I didn't follow up on that)
