Dun dun DUN! Blizzard bannage.
According to the World of Warcraft community site, Blizzard's banned 5,400 accounts and suspended 10,700 more since patch 1.10 went live the week before last. The reason? Widespread looting and violence caused by the Blizzard's April Fools' Day jokes? Nope.
Razor (over at Warcry) believes this will only result in 5,400 more copies of WoW being purchased. If he's right, what a deliciously Machiavellian marketing ploy.
