I got my STEAM acc banned by Valve anti cheat 2 days ago... And no i didn't hacked.
And this is not the end of story.
Tonight i got a letter from a president of Valve.
That it was their fault.
Hello,
Recently, your Steam account was erroneously banned from Call of Duty: Modern Warfare 2.
This was our mistake, and I apologize for any frustration or angst it may have caused you.
The problem was that Steam would fail a signature check between the disk version of a DLL and a latent memory version. This was caused by a combination of conditions occurring while Steam was updating the disk image of a game. This wasn't a game-specific mistake. Steam allows us to manage and reverse these erroneous bans (about 12,000 erroneous bans over two weeks).
We have reversed the ban, restoring your access to the game. In addition, we have given you a free copy of Left 4 Dead 2 to give as a gift on Steam, plus a free copy for yourself if you didn't already own the game.
Regards,
Gabe Newell
President, Valve
Sad side of this story is that i already got new acc and buyed a game to make it active...
