Background of Issue
This type of spam has been around since the advent of guestbooks and search engines. It first appeared in Internet guestbooks as posts to the guestbook with a link to their own site and with no actual comment. This link was intended to help ranking the site to which the spam was linking better on search engines. If an actual comment given was usually something like "cool page", "nice website", or keywords related to the spammed link.
In 2003, spammers started to take advantage of the open commenting systems in blogging software like Wordpress and Movable type by placing comments to other blog posts that provided links to the spammer's website. Many blogging software packages now have modules available to them that can block this kind of spam by making it difficult to automatically post on such blogs or actually reviewing and rating the URL provided to determine if it is allowed or not. For every tool to stop the posting of forum and comment spam there are tools to circumvent them.
