Webspam, AdSpam, and Webmaster Guideline Violations
The Google Ads policy on webspam, ad spam, and webmaster guideline violations will change around late February 2011. The policies are changing to simplify our policies around spam-related issues. The change will affect all countries. We made this decision in order to streamline our policies and eliminate confusion among advertisers about our spam-related or webmaster-related policies. After the new policy goes into effect, the policy description will be updated to reflect this change.
