I legally play the counter I do not cheat if I have made traders in skinclub but why many do it but I have never used any kind of hacks or anything I have been playing counter for a long time and when I entered my steam account I saw this: Dear xxcesarapxx, The phone ends with * 64. This account has been flagged as suspicious for violation of the Steam Terms of Service Agreement. You will not be able to play on public servers of Counter-Strike: Global Offensive and you will not be able to exchange any item in the game. Trading in the following account will be permanently deactivated in 1 hour. We are sending this notice in advance regarding the User Information Policy as we received many complaints that people lost items and were not warned.
