JenSense has posted an officially sanctioned way
to report Google
If you see a site violating the AdSense terms, you can now file an anonymous spam report that will get to the quality team for checking. To file a report, you simply go to the page that is showing AdSense ads and click on the “Ads by Google” (or “Ads by Goooooogle”) link. In the form on the next page, include the term “spamreport” and put in a short reason about why you feel the site is violating the AdSense terms or policies. You can also enter your own email address, if you wish, then click submit.
In a similar vein, Pascal Vanhecke has a post suggesting methods of reporting spamblogs using social networking tools like de.licio.us and Furl.
Why not lend Technorati (et al) a hand and tag the spamblogs that slipped through the net. If you get annoyed by a Spamblog showing up in your Technorati Watchlist (or Google Alert, or any other search feed), report it, tag it: “spamblog” * ! You could use del.icio.us or furl, the services that are being aggregated by Technorati.
I know I’m beginning to get a little irritated with the spamblogs that clog up my PubSub feeds now and then, though I’ve never gone through the trouble of reporting any of them. The process is just too inconvenient.
What is really needed is for all these services (PubSub, Technorati, Blogger, Google, etc) to come up with a common reporting format that can be used by all parties as a first line of defense against spam.
Imagine being able to report a site to ALL search engines, RSS aggregators and blog hosting services with one form. THAT would be ideal.
