A couple of weeks ago, SixApart launched a new blog anti-spam software called TypePad Anti-Spam which aims to compete with Akismet and Defensio at combating comment spam in both TypPad/MovableType blogs and WordPress blogs.
The TypePad Anti-Spam will have the ff. features:
* Plugins for Movable Type 3 & 4, WordPress 2.5. Yes, it works for WP too! There’s no usage fee for commercial use. Akismet charges $5 per month if your blog earns at least $500 a month.
* Open Source. You can download the source code and modify it to your liking to extend its features and functionalities. Akismet has an open API but is not open source so you don’t have access to its codebase.
* 100% Akismet API compatible. Works with Automattic’s Akismet too.
I’ve tried switching from Akismet to Defensio then back to Akismet, then now to TypePad Anti-Spam too see which of them will filter out the most number of comment spam on this blog.
We’ll see in a few weeks. Download the WordPress plugin here.
