Blizzard Sues Bot Creator; Seeks Customer Info

An anonymous reader writes: After filing a prayer for relief to continue the selling of his WoWGlider, an automation bot for Blizzard's fanatical World of Warcraft, Michael Donnelly has again found himself in some deep water: Blizzard has retorted demanding WoWGlider be shut down, his URL, and financial compensation, but more interestingly they want all of WoWGlider's sales records. Presumably, Blizzard will cross-reference this with their current user database and ban anyone who bought the program. Furthermore, Blizzard claims that WoWGlider violates copyrights by accessing the game client's RAM space, a process which is also done by every anti-virus program. So why is there no Blizzard vs. Symantec?
