This picture, available in greater detail here, comes to us from Sid on Proudmoore.
Apparently, a certain gold seller got creative when trying to figure out ways to advertise past Blizzard's spam filter. The gold farmers created hundreds of identical level 1 gnomes, postion-hacked them into mid-air, and let them fall to certain doom in a way that spelled out the web address of their gold-selling site, which I'm not going to name here because I don't want anyone to get keylogged or anything. Looks like they've lost part of their "W", though. Players on Arthas, Frostmane and Eitrigg have reported the same tactic by different companies.
This makes me kind of glad I'm Horde, because I can't see anyone finding enough flat ground in Orgrimmar to do this successfully. I also have to give credit to the gold sellers for trying way, way too hard on this one. Taking the time to make all the level 1 gnomes, hack them into midair, and then arrange your company's name for ... what? Is there anyone out there who actually sees gold selling advertisements and goes, "Gee, buying gold. I never thought of that before, but now I will visit your lovely web site. Thanks, Jmhmltcawf/random dead gnomes!"
What's next? Raids made of gnomes whose names, read in conjunction, make up an advertisement, kind of like those old Burma Shave signs?
Thanks for the tip, Sid!
