There's a bunch of right wing trolls who filmed themselves signing up & posting really shitty mean things. These are not well intended people; this is boundary pushing. You either lose by becoming a Nazi bar, or if you listen to them you lose by having their snivelling crocodile tears to deal with forever.
These folks can go run their own PDS! But generally I think nothing of value was lost, that the network has rightly refused to let itself be degraded.
Also, I suspect there was something else going on there, because there are lots of bigots on Bluesky. The “Very British Bigotry” blocklist (for fancy modern/Rowling—style transphobes), say, has literally thousands of people, completely unbanned, on it; Bluesky is really fairly small-l liberal about post content. One thing that they’re somewhat strict on is profile content, and I would speculate that those performatively getting banned are doing so on the strength of putting shit in their profile.
