Unfortunately I doubt goblin will tone it down, or disappear. Doesn't matter how much people tell him he's a clown. In the past, people called him on his fabrications about trades. He then shuts up for a day or so, and comes back.

What I do is just put all his screen names on ignore. This can only work, though, if nobody engages him in conversation, otherwise his threads still show up.
