Blue poster Nevalistis wrote a very good post about player rights, Blizzard on player infractions, and basically pwning whiners.
Players: WHINE WHINE YOU DON'T DO ANYTHING ABOUT JERKS!!
Nev: If you don't report them, that's true.
Players: WHINE WHINE YOU DON'T CARE ABOUT US, YOU ONLY LIKE MONEY!
Nev: Then why do we spend so much to employ GMs?
Know your in-game rights.
