There are some cub artists with a pretty decently-sized following who post almost all of their art to Bluesky and still haven't gotten banned.

I guess it's because they don't generally have much nudity? The ones I'm aware of are diaper artists mainly, so there's generally clothing covering up genitals at least. But the actual art is pretty clear about very lewd stuff and very young characters. Visible cum, erections, ahegao, etc.

It's probably just a matter of time, though.
