I got banned at least once in game and multiple times on the forums back when the server was first returned after the co-owner fiasco. To be fair though, I was being edgy™ and all around a bother to the staff. While I'm still not sure it warranted a ban to the extent I got, I can see why they (and more specifically, Coelho) felt the need to ban me.
Since someone knocked some sense into me I've been a goody two shoes though, although I think once or twice when I was staff I was banned to test something. It's been awhile, I can't exactly remember.
