Bluesky is supposed to be, rules and admin-wise, Twitter before Musk took it over, i.e. Leftist-style "free speech". It's more about the political/gender stuff and less the nsfw artistry.

Musk's attempts to monetize Twitter screwed up the algorithms and reach, and while the Leftist bias in "Trends" went away, organic growth is pretty much gone for various types of users that didn't already have enough followers, especially artists that do even mildly sensitive work. There's enough traction on Bsky now that more and more are jumping ship even though Bluesky has its own breed of censoring.
