I've really only trolled trolls in the past. If anyone is den claiming for example, I'll come in and sit to antagonize them (and even made a game out of it with friends before seeing who could score the most points) . Honestly, if you're a den claimer and REALLY make me angry though, I will advertise via movie clips (and used to on General whenever it was around) that there is a den claimer in such and such den and that everyone is welcome to come on down and sit in the den.
