CNET News.com: "Researchers at Microsoft have developed a tool to scrub search engines of major Web sites that pollute search results and ultimately help clean the Web of spam.
Called Strider Search Defender, the tool is designed to dig out Web pages that are a front for spam Web sites, according to a paper published by Microsoft researchers on Thursday. These Web pages typically reside on blogging sites and other services that provide free Web space, the researchers said.
Spammers soil the Web with countless links to their spam fronts in order to gain a higher ranking in search engines. 'By cleaning up Web search, hopefully we can discourage spammers from cluttering the Web with spam,' Yi-Min Wang, principal researcher at Microsoft, said in an interview. "
