You get trolls on every site, the bluesky ones are the worst. Because they don't think they're trolls. They think they're valiantly saving the country by quibbling with leftists.
I have to guess (because I don't know from experience) that having more than ~10k followers on any platform exposes you to much more of this. I see the same complaints from people wth a large following on Threads, for example.

Social media doesn't scale well. Humans are poop sometimes.
