Hello, i've to say it right now, i'm French and i don't wrote english very well, so sorry for the many mistake i can do. My brother play on my Steam Acc and ban me for use a cheat. I don't give a shit about this but i want play quickly. My question is : Can i take ArmA on a second account for play ? I mean, if i buy a second, i'm ban on the second too ? The BattlEye ban the MAC Key, or the ip, or only the account ? Sincerly.
