Here’s a post from 2021 about this person giving some background. I recall even a change.org petition requesting them being banned.

Also, you might recall them for making the news recently after banning an artist from /r/art because they said a piece by them was made by AI, and when proven otherwise they said that it was obviously based on AI and that they should find a better style, which escalated to the point that the sub was temporarily closed

Seeing that person going down is a nice piece of justice in this shitstorm. It happened for the wrong reasons, admins should have removed this person long ago and didn’t, but at least it’s something.
