Is Google involved in the selection or registration of the domains in the AdSense for domains program?

Google AdSense is not involved with the selection or registration of domain names. Google adsense encourage trademark owners to resolve their disputes directly with the registrants or registrars.
Google provides a simple publicly available complaint procedure as a courtesy to trademark owners. Once Google adsense notified of a legitimate complaint against a specific domain, Google will no longer serve ads to that domain. For instructions on how to file a complaint, please refer to the Trademark Complaint Process page. A copy of Google Adsense publicly available trademark policy is available online on internet.
