Here is a few things that I've found and Tested.
Fist of all, Its a great work but still he could skin the other teams in blue.
Second , In-Game don't ever press F12

or just unbind the ScreenShoot function because most of them are Shared ones.
Third , Some how my other steam account got vac ban , the only thing was there is those files in the iwd.
So to answer you guys Safe or not i dont know, maybe the guy that i hacked was with cheats i dont know...
or Maybe some jerk just reported me... well i dont actually care about this steam acc... but i really want to figure out why the acc were banned.
Oh another thingy , All who own mw2 and its vac banned , Black ops will not be banned ... everyones talking bullshit..
