They banned a bunch of people including Jessie Gender (now reinstated) for mild criticism of the Harry Potter author.

They banned people for posting old (public domain) short films for fictional violence.

There was another ban wave when people were criticizing the hateful words spoken by that one guy who was violently killed.

There's an explicit promise of an upcoming wave of noncon artists. (I'm personally not a fan of such art but don't think they should be banned)

Some people have been reinstated, but the explicit focus on limiting speech has a real chilling effect.

I'm positive I've missed some from longer ago.
