www.survey-machine.com has been failing automatic validation again, as of about a week ago or more. Before, when I had less pages on the site, I could just click "revalidate" 20 times until it works. Now that there are hundreds of thousands of pages, that doesn't work so well.
Ads need to be placed on every page. For example this one is cached at Google and has no coop ads on it http://www.survey-machine.com/view_survey/103
