Cant remember that last multiplayer game I completed without some pain in the ass hacker / griefer ruining the game completely. It has stopped me playing Alpha for the moment... thinks "what will I play?? Arma 3?.. nah too many hackers, too much hassle.... BF3 it is then ??.."

Is there any way that the security can be turned on? I know that lots of people hate Battleye, but the situation at the moment without any anti-cheat or security is just impossible.
