Spammers, unscrupulous lot of human waste that they are, have started using Google’s Blogger as a new way to drive traffic to their sites. Given the increasing effectiveness of filters to block e-mail spam, we can expect to see more of this Google spamming in the future.

According to an article on WebProNews spammers are signing up for and establishing dozens of free blogs, then littering the entries with key-word rich links to the pages where they sell their crap. The number of links to these pages boosts the page rankings in the Google search engine, which relies heavily on links to pages as part of its ranking formula.

This practice won’t hurt blogging like it hurt e-mail, since there’s no reason you’d ever visit one of these blogs. But it could render Google ineffective when the top search results all take you to a site that wants you to buy products to enlarge your genitals or take out a mortgage.
