Hello, my gaming name is BORIS and my steam id is STEAM_0:0:92165

Basically, my obnoxious roommate got onto my steam account, started up cs and team flashed and harassed the server, typing stupid things.  I got back late that night and wanted to play cs and started it up and found out I had been banned from all warlord servers.  I asked my roommate if he knew anything about this and he said he messed around with my account.  I was pretty furious because i'd like to use these servers.  Is it possible you can unban me?  I'll make sure my asshole roommate stays away
