I haven't touched the Block button for a while, actually. I even regret blocking the majority of my blocked users, and would gladly unblock them if I could recognize the username. The reason I haven't already unblocked any is that I can't tell the difference between the innocent ones (ones I had blocked because they were in "clan territory", which at the time I didn't understand the meaning of claiming(I had just started)) and the actual trolls and cursers. I think I'll just unblock them all sometime, and re-block the ones who are truly bad or trolls. I usually block people for:
~out of hand cursing
~over reacting to RP drama(I once was re-elected in place of a pack's current Alpha, who later Power played an attack on us o.O)
~insulting the game and/or a moderator or member while OOC
~Extreme Power playing
~Extreme trolling
