If it's an offender, than you throw him out of your game or go find a new one. Denying someone the use of something just because someone else might be a complete moron about it is completely ridiculous. You haven't even given it a trial yet, you've just made some judgment based on a phantom offender stalking the halls of the RPF who might be a twit about a rare situation involving PVP. If you have the power, then turn it on for a trial period, say a month or so. If you receive too many complaints, turn it back off and we'll know you were correct in your assessment. If there aren't any complaints, then everyone wins.
