AntiSpam – Looking Beyond Akismet
Akismet- the antispam plugin bundled with WordPress is a lifesaver. It really is. But, it is far from perfect. Its does occasionally let a spam comment slip through or give false positives. Here are two worthy free alternatives to Akismet that you can consider.
The first option is Defensio by Karabunga Inc which claims an average accuracy of 99.77%! Defensio uses an adaptive, personalized filtering algorithm.
It scans your blog posts and tries to determine how relevant the comment is. One of the most useful features of Defensio is that based on a number of factors is assigns a score (called spaminess) to each comment. You can arrange comments according to spaminess. This allows you to easily detect false positives. Bloggers love stats – in fact most of them are obsessed with them. Defensio’s detailed charts and stats would definitely please a blogger. Defensio even provides RSS feeds so that you can track your comments and spam from anywhere, without even logging into the control panel.
Launched less than a month ago, the TypePad AntiSpam by Six Apart is already making waves. It has found high profile backers like TechCrunch. Michael Arrington found Typepad Antispam is significantly less prone to false positives. I am currently using this plugin for my blog. Typepad Antispam is also Open Source. Six Apart is open sourcing the core engine, allowing others to build on top of it allowing them to build and operate their own spam service. Six Apart claims that they are not revealing the basic algorithm powering their spam filter, so this won’t reduce the spam filter’s effectiveness but plugins will increase the utility of the end product.
