Apparently Microsoft has been working on a new technology that will scrub your search results of “spam” websites. Spam sites are typically those sites that are created with no real content or purpose other than to funnel traffic through to an advertiser or profit generating site. The most common of these are called “doorway pages” but other a new kind of spam using blogs has also become mainstream for search engine spammers. The new approach is a basic, if novel, idea:

Microsoft’s tool doesn’t find spam the traditional way, by looking at the site’s content. Instead, it turns the spammers’ activities against them by using search engines to find links to potential spam pages. These links are often posted as comments on blogs, in online discussion forums and in guestbooks, also called “comment spam”.
