I largely ignore it, they'll either drop or the run will be over soon enough that I'll never have to deal with them again. Trying to exact. "Revenge" is just stooping to their level and perpetuating the cycle, you've gone from being a "victim" to just another jerk.

And once the kick feature is added, if 3+ jerk in a group want to boot me from the group for spurious reasons , then I'm sure I wouldn't have enjoyed my time with them anyway. So I'll just reque and hope for a better group, no sense getting worked up about not getting to run with people I wouldn't get along with anyway.
