If you’ve been using WordPress for some time, you’ve probably noticed comment spam — comments that sound really nice, but have really been setup to link back to their business when/if you accidentally approve the comment. The more popular your blog/website, the more you’ll likely receive. One of the best solutions for combating this is Akismet which is provided by Auttomatic, the same people who run WordPress.com. They have setup the service free for personal and non-business blogs. Once activated on your site, whenever someone comments on your site, it will send that comment to their servers to be reviewed. Because Akismet monitors millions of websites, their engines have a pretty good idea if that comment is likely spam or legitimate. If it shows up as spam, they’ll do the hard work and delete the comment for you, only leaving up to you to approve or trash the human entered comments.
