Related to link spamming is comment spam. Comment spam is where a spammer visits a
publicly accessible site and deposits a comment with an anchor text link back to a
designated site. Forums and blogs are typical target. This activity became identified as a
major problem in January 2005 when Google took steps to prevent it from the blogs of
Blogger.com. The reason was that spammers working for so called PPC (Pills, Porn and
Casino) web sites were trawling legitimate blogs and posting uninvited comment
advertisements with their web site’s anchor text. Blogs were vulnerable because they
typically possess a comment section that can be accessed without the need for passwords
or even registration.
