volume detection

I'm tired of people in combat sims that will wait till the admins are gone then fly around with volume detect off. Thus rendering them untouchable by anything. why even bother going?

Now is there a way to trip the volume detect back on with out having the avatar sit on anything? I'm guessing not

Not all meters use collisions so they are not effected. I always though it was because of lag, but I guess they knew about this along time ago. If you catch someone using it and no admin around, it yourself and so who can out god-mod the other. They will get tired.
/me goes off to Rausch and see how long people will shot at me before giving up.
