How about Google pay people say like $5/site that people find in violation of it's Adsense TOS? That way, they'd have tons of more bounty hunters! I call first dibs on Doug "The Bounty Hunter". *singing* I'm the Doug...the big bad Doug....The Google Bounty Hunter Yeah! *laughing like Dog the Bounty Hunter*
They know who the violators are. Search for "banned for no reason" in this forum and you will find out who they were last month and check next month for this month's violators. It's funny how now of these people ever posted "I got approved for Adsense for no apparent reason".
lols google can easly place a algo on your site and the adsense to see if the match ... so they now ! at least of a lot of them !
