Sick of blog comment spam? Use Akismet
September 28th, 2007 Enabling visitors to post comments on your website is a great way to interact with your audience. However, unwanted advertising has polluted this feature in recent times. As a result, 93% of all comments nowadays are actually spam. Who has the time to sort through all that junk?
Fortunately, there’s Akismet, one of the most popular comment spam blockers. Its name was inspired by Kismet, the Hindu principle that means “the magnetic attractive force that actualizes the playing out of karma; often used in the positive sense.”
When a new comment, trackback, or pingback comes to your blog, it is submitted to the Akismet web service. It then tags it as either spam or not, based on tests performed on that comment. A spam is stored for 15 days to give you time to check it out manually, before Akismet automatically deletes it. In case something gets incorrectly identified as spam you can correct it and the plugin submits the feedback to Akismet for analysis and improvement. The same thing happens if a spam comment happens to get through and you mark it as spam within WordPress. Akismet becomes more effective the more you use it. No need to maintain a lengthy blacklist or check for upgrades. With Akismet, you’re always protected from spammers’ latest tricks.
Akismet has gained wide acceptance among WordPress users, however you can use it on virtually any application with submitted content, like forums, wikis, and contact forms. You must register for a WordPress account and get an API.
