He hasn't been banned from here, at least not permanently. He hasn't appeared on the forum since August 2015, though.
He crops up on various groups on Facebook that I'm passively involved in.
It's always a countdown until one of the moderators has had enough of him, and he moves on to the next one.
This is pure observation. I have no beef with him, nor have I ever really interacted with him. He just seems to bring the wrong sort of gift to every party.
