World of Warcraft Account Bannings

Blizzard Entertainment has announced that they have banned several thousand World of Warcraft accounts for using programs that automate player actions.
In the US and Europe, we recently banned several thousand accounts associated with the use of botting programs that fully automate player actions, such as killing and looting monsters. We take these attempts to bypass the rules and standards of the game extremely seriously, and we will continue to aggressively monitor all World of Warcraft realms in order to protect the service and its players from the negative effects of cheating.

By my calculations, the game only has about 9 million paying accounts left after these bannings. They better do some cost-cutting or they could find it hard to pay the bills with only $100 million/month to work with.
