Mw2 Lib 1.4

Maybe if you have buyd like 20 account. Maybe they IP ban you. But who knows what they might do....

What you are thinking about is that all games on that account gets banned when using Liberation. There is no reason for them to check which accounts are connected to your account..

But, I know lib messes with the steam installation, or at least thats what I heard. I think its unlikely that he will get banned on another account, but I know people have had every game on their account banned for using lib, Source engine or not.
