I just be banned in L4D2 server and I don't know why. I just got in the safe room first and wait others come. I mean I got rank of 80 in this server so I know what I am doing. I can prevent my teammates be pulled or other in the safe room so that I dont know why i was banned without any explanation. It might you do not like get in safe room alone but I think you should tell me before I was banned permanently.
