I honestly didn't think it was this bad, but the fine folks over at the Fires of Heaven forums have proven me wrong with some screenshots of recent "hacking" done on many US realms.
Apparently a certain unnamed gold farming website is employing a new type of spamming in-game. It's hard to believe, but they're literally spelling the URL of their website out in dead gnome corpses in the middle of Ironforge, by hacking the client and flying into the air, then dropping from the sky - falling to their deaths. There are several different sources for this; the FoH thread I mentioned above and two threads on the official forums - one in General and one in Customer Service.
