Therein lies the question: did you bite? I can see arguments for both sides: maybe you stood your moral ground, said that that gear wasn't really supposed to be free, and didn't try to take advantage of a mistake one of Blizzard's coders made. Or maybe you said, "well, if it's on the live realms, it must be legit," and looted as much of the gear as you could (and maybe you're paying for it, too, either now or later this week).
So what'd you do? This isn't the first time a game-changing exploit has made loot accessible to players when it shouldn't be, so if given a possible exploit in the game, do you grab away and let Blizzard worry about their own mistakes, or do you decide not to take advantage of mistakes Blizzard didn't mean to make and wait for them to fix it while you do things fairly?
