Looking through, it was his 3rd time up.
November 18- heads up, inappropriate content with minor, including incest
November 28- final warning, inappropriate content with minors
The July 12 ban for inappropriate content with minors was the last straw.
For what it's worth, I saw a post by him the other day which was truly breaking the rules regarding minors. Not sure if that's what got him the ax but if it was I am not at all surprised. It was a disgusting post, to put it mildly.
