Hey guys, I know it's easy to say this now, but this things usually work out in the end, you know? It takes a little patience, and for a while, you or your friends get shit on, but the thing to remember is that people like this never last for long. And the only know method for defeating an internet troll is to ignore them. If anyone finds another method that works, great, but for now that's it.
And if anyone really thinks that the "chill out" and/or silence from other posters was an endorsement of the irritant over them, then they really are underestimating and insulting the rest of us. Heck, I did that myself before with a certain SACD lover. I argued and stormed and fretted, and in the end I finally realized "hell, everyone else knows he's an asshole just as well as I do; why am I trying to prove it?"
