You need to grow a skin, in the first place, if a simple /emote in a game where player-versus-player combat exists offends you this much.
Like you. I know.Some people need to grow a thicker and functioning brain.
Welcome to PvP. It's called "taunting".I can recall many times where I have been died or been killed and been called derogatory names and then spit on.
The whole purpose of a taunt is to get under the opponent's skin. Looks like it works beautifully in your case.It's rude behavior,
The fact it affects you this much says a lot about you and your maturity.immature and quite disturbing since the average age of the playerbase is around 23-30yrs.
