So basically I was messin' with Strings by copying his name and replacing the "spacebar" with alt cote 255. Apparently this is auto detected by the server scans and I was banned :c I didn't mean any harm by it and everyone had a good laugh. Being unbanned would be a very nice thing though.
Edit: I was playing on the DBS server, and my stean ID is STEAM_0:0:34153768
