Alexander was perma banned the other day (Sat or Sun can't remember... King Banana will know) and I haven't seen any demo or posting as to why he was banned. This occurred when pub was down I think and 2 admins normally on pub came into gg. I know one of them was Decoy.
These admins were in for like 5 mins when they muted Alexander. Many players asked them why he was muted and they would not give an answer. After a few rounds Alexander was unmuted. He said some negative things to the admins and they perma banned him. I'll admit that he shouldn't have gone off on an admin... but they wouldn't tell him why they muted him. Also I don't think what he said to them was grounds for a perma ban... which to my understanding requires a demo and a posting in the "Bans" section anyway.

King Banana was there the entire time and has talked to Alexander since... Maybe he can add some details which I wasn't sure about.
