Google killed the AdSense account of an anti-scientology site - Enturbulation. Google's explanation to Enturbulation was: "While going through our records recently, we found that your AdSense account has posed a significant risk to our AdWords advertisers," read Google's letter to Enturbulation, a kind of home base for the now famous Anonymous movement. "Since keeping your account in our publisher network may financially damage our advertisers in the future, we've decided to disable your account."
