hahahahahahah. I think the best part is that they either:
a) Have a generated e-mail for this sort of issue.
b) Have an employee humorous enough to write an e-mail that seems generated.
It seems it'd be a good public relations move for Blizzard to have generated emails of this sort. In the case a kid does commit suicide over WoW (very possible), a news article could say, "Kid commits suicide over Blizzard game," versus, "Kid commits suicide over Blizzard game despite Blizzard's attempts to stop him."
