I have for long noticed the "Report a spam site in our index" link in the Google webmaster tools. I have long heard and believed that Google employs a large army of reviewers who review and rate sites all day upon several parameters. The army is a major driver of the search engine's capability to display quality sites and to remove the affiliate, MFA, copycat and other spam sites from the index. So the great SEOs may have good tips about how to get past the manual tests? And has anyone ever reported a spam site using the link in webmasters tools?
