Bye bye to (some) MFA sites

At long last Google are about to do something about their bastard step-child, the Made-For-Adsense (MFA) site. It surely can't be too difficult to detect them - they contain multiple blocks of Adsense code, no links to useful resources, sparse content, and usually no contact details. They tend to be on domains with hyphens in them, and tend to get all their inbound links at once. As of June 1, Google will begin a purge of these from their index and/or removing them from the Adsense program:

Google says the clean up will affect the Internet, primarily by cleaning up search results so that users don't click through to a site filled with ads but with no content to support the ads.
