Which method are you referring to? Ardivaba2's no bybass method? If so, I have used it on a good few servers without hassle; there is no point looking for one particular server to test it on. It either works or it doesn't - BattleEye is the same on all servers, even though admins may not be. If you do it right, and do it in moderation then you should be fine. But as with all hacking, there's always a risk.
