@FaLLeN players complain because you play very well as infected.
My suggestion is that you bring a little more balance to the game, in the sense:
start as a player and buy a couple of good weapons, first aids, etc.
(if there is no one else to do it and often there is not) , and then change sides.
I hope that you will get your privileges back soon, because I'm waiting you - with a shotgun
