Anyways, the best solution I can think of for weeding those people out that I see used is to say in the PF that 1 or 2 death will result in their vote kick. Must have cleared previously or be kicked. No tome bonus, Etc. Make it known that deaths aren't tolerated and only serious people need to apply.

Probably more trouble than it's worth but you can try to check their achivements. Eitherway, just blist those people
