You need to develop thicker skin, my friend. People are gonna criticize you all throughout life... especially in World of Warcraft.

Don't ever let it bother you.. Say nothing but grats, put them on ignore, and definitely report them for foul language. GM interaction is quite often the best way to get someone to leave you alone. Heh, I used to flame so many people until I got a suspension, then it all changed.
