Ever since we installed Comment Guard Pro, anti comment-spam plugin on this blog, it stopped over 1 millon spam comments (1001011 spam comments were blocked by Angsuman's Comment Guard plugin in 335 days 8 hours 38 minutes. 99.338 % of the comments received during this time were spam.) so far (look in the right sidebar for latest stats). The pro version of the plugin is now being tested on this blog and other sites.
In Comment Guard Pro have developed multiple layers of defense to stop all kind of comment spams - spams submitted using comment forms (robotic or by humans), pingback spam, trackback spam and referrer spam.
