Our AdSense Policy and Ad Traffic Quality teams work hard to find implementations like the one you described and we're constantly working to improve our systems to detect this.

While the invalid activity form is intended for publishers to report activity on their own sites, it is good feedback for us to provide a formal avenue for notifying our team of violating sites and implementations.
