This could be an interesting thread. What are the most infamous or well-known events/bugs/exploits/glitches/things that have happened in WoW's history?
Something like the Corrupted Blood Plague, 80s soloing MV, DKs killing friendly players, Reckoning bomb, Shandris Feathermoon, etc; crazy and infamous things that have happened in game.

-Corrupted Blood Plague
-Saronite Bomb LK
