World of Warcraft
World of Warcraft (commonly abbreviated as WoW) is a MMORPG played by millions of people.
Warcraft YTMNDs
YTMNDs created with WoW involved are typically frowned upon by most YTMNDers. WoW sites often receive tons of views because they are posted on the WoW forums, and are upvoted by these viewers even if the site is subpar. Many of these sites contain inside jokes that only WoW players understand, and thusly most WoW YTMNDs are downvoted into oblivion by the standard YTMND users. Eventually, a WoW site was hacked (by Max, reputedly) and replaced by an image containing gay pornography. As the site had doubtlessly been linked to WoW forums repeatedly, it was hoped that this would serve to tell the World of WarCraft community to stay away from YTMND. The creator of that site was notdsk who is listed as part of the YTMND staff. This fact supports the possibility that the site was entirely intended as a set up.
Despite the hatred of WoW sites, there have been a couple which have been relatively well-received. The fad Leeroy Jenkins is based on a video of several WoW players. In the other direction, the World of Warcraft website makes reference to Safety Not Guaranteed on this page (Mouse over the dragon).
The famous site Wow is serious business doesn't actually take place in World of Warcraft, but in a different MMORPG called Dark Age of Camelot.
