I agree with the need for rule enforcement, and Sarah, this is not a criticism, no one expects you to be online 24/7 and I also know how protective you are over your creation.
Perhaps an item could be created to be given to some select demi-dm's to allow for a certain amount of control over booting trouble makers or sending them to prison and clearing mass mobs in dungeons etc..
As i have probably just given away, I know nothing of scripting so this may not be feasible but its just an idea. Failing that the only other alternative is picking some trustworthy players to give DM access to.
