WHYBANME

I was playing Left 4 Dead 2 on gcftw.com L4D2 10V10 #1, joined the game normally. So when I started playing as survivors, i played normally like everyone else, i did not friendly fire, i did not do anything. When I got to the safe room with 3 other players, grabbed some supplies then I JUST GOT BANNED SUDDENLY!!!!!!!! I don't know if admin mistaken me with other people or just being a jerk or what. PLZ UNBAN me, THANK YOU VERY MUCH. MY Steam ID: STEAM_0:0:26830026
