Google has released its 2013 report on advertising.
By the end of 2013, we had blacklisted more than 200,000 total publisher pages, an encouraging decline from last year, and disapproved more than 3,000,000 attempts to join our AdSense network. We also removed more than 250,000 publisher accounts for various policy violations. This includes more than 5,000 account removals for violating our copyright policies, an increase of more than 25% compared to 2012.
