Ideally, we'd all shoulder some of the responsibility of keeping our online community balanced and clean. Even in the best of circumstances, though, being the squeaky wheel is no fun. Whiner, snitch, tattletale -- there seem to be plenty of labels for players who are simply letting Blizzard know that another player is breaking the rules. Thing is, it's up to us to get that job done. Blizzard can't be everywhere at once, but we can -- and are.
Do you take the time to report problem behavior in game? If so, do you tend to stick to cases of personal harrassment? Do you bother to report spammers? What about problem players in the dungeon finder or raid finder -- do you let a kick "take care" of them, or do you follow up with a report?
