Steam unbanning... no...
I believe i know what did it, i have Teamspeak Overlay, which hooks into DirectX. Punky kicked me from AA and BF2, etc, for running it and have since had that hardware ban resolved. Steam have refused to unban me even though i have permitted them to search my computer for anything, and my internet logs, etc. They have a zero unban policy, and by doing that they contradict their own EULA, "We will never ban accounts for no reason", but they are not telling me the reason!
BTW, it wasnt CS: S, i was banned from CS 1.6, not the end of the world, but if TSO is going to get me banned, i am not going to buy any steam games. It is a good program, Punky updated their detection against it, so why cant Steam and VAC?!
