Sounds like **** or ******* . I don't know why your friend's so easily run off, but one of the issues with interacting with people online is, well, interacting with people. There are a few in every bunch, and the most notorious in AH figured out that they won't get muted if they PM, and the .report command is a joke, so they know they're not going to be punished, unless the person they're harassing takes a screenshot, composes a short email, and fires it off to HTC. Granted, that's not too difficult, but if HTC got an email for every one of these incidents, he'd spend all day on email.
You should never take anything from those losers seriously in any way. I've received numerous physical threats, unpleasant comments regarding my parents, been screamed at on private vox, and called every name you can imagine. *shrug* No big deal to me. If grown men want to act like 12 yo boys and squeal because I killed them, terrific. I admit I like to wind some people up, but by and large the community here is a good one, and letting the fraction of 1% that are idiots run you off is silly.
