Akismet is a spam prevention tool that we provide to you at no additional cost.
It checks the comments on your blog posts against the Akismetweb service to see if they look like spam or not and lets you review the spam it catches under your blog's "Comments" admin screen.
Each time a new comment, trackback, or pingback is added to your site, it's submitted to the Akismet web service which runs hundreds of tests on the comment and returns a thumbs up or thumbs down. As a result, you don't have to waste your time sorting through and deleting spammy comments from your blog.
