He didn't use my ads but I wonder what happens if he do?
Is there any way to block sites from unauthorized adsense
May I report that to Google?
Sure there is a problem with your site being stolen, but at least you are getting income from visitors to that site. Doesn't rank low in terms of losing your site?
If you don't want the income tell the thief to get his own adsence account and change the ID over ...
What is theproblem with other sites using your adsence code?
And I agree, having a white list/black list feature (or at least a list of sites where your AdSense code is being displayed) is a much-needed feature on AdSense.
