It saddens us to close these services, but the recent advancements from Blizzard's side are only possible because of their decision to compromise the privacy of their players. While WoW runs, the game is continuously scanning the user's computer with the capability to send back exactly which applications the user is running, and in some situations even going as far as sending back window titles of any window on the computer. These things happen even if WoW is running in the background, and even without logging in to a character.
