Google Banned 800,000 Advertisers For Malware, Scams, and Counterfeit Goods and Services [googleblog.blogspot.com]

The numbers show we’re having success. In 2011, advertisers submitted billions of ads to Google, and of those, we disabled more than 130 million ads. And our systems continue to improve—in fact, in 2011 we reduced the percentage of bad ads by more than 50% compared with 2010. That means that our methods are working. We’re also catching the vast majority of these scam ads before they ever appear on Google or on any of our partner networks. For example, in 2011, we shut down approximately 150,000 accounts for attempting to advertise counterfeit goods, and more than 95% of these accounts were discovered through our own detection efforts and risk models.

Wow, that's a lot of accounts scamming.
