The constant roleplaying by some members of the fandom. And this is coming from a veteran seven year Moonguard player in WoW, and officer of an RP guild!
I mean seriously, you don't need cute little elaborate emotes at the end of every sentence, you don't need to *glomp* or *huggles* people constantly, if someone is trying to have a normal conversation with you then you don't need to try be all cutsey and type out your every hypothetical action, just talk to them like a normal person. You don't need to shove your RPs down the throats of everyone nearby and get all pouty in your emotes when they don't respond to your *pouncehugs*.
