TypePad AntiSpam, A New Open Source Comment Spam Fighter

(...)

TypePad AntiSpam is clearly aimed at Akismet, a similar spam fighting tool offered by arch-rival Automattic. Like Akismet, TypePad AntiSpam takes a multi-headed heuristic approach to detecting and blocking comment spam on blogs. But TypePad’s product is free - Akismet charges $5/month for commercial blogs making more than $500/month in revenue, and has performance limitations on the free version.

TypePad AntiSpam is also open source, and anyone can download the source code and create their own spam tool based on it. Akismet isn’t open source, although they have an API that allows developers to, among other things, develop additional integration tools for blogging platforms.

We are long time users of Akismet on the TechCrunch blogs, and I’ve included it in my last two yearly lists of products I can’t live without (2007, 2008) along with Wordpress, Automattic’s blogging software. Akismet blocks over 15,000 spam comments per day on TechCrunch.

Twice now a large group of spam comments hit the moderation queue, but Six Apart says it was their system thinking we were under a denial of service attack from the sheer flow of spam attempts and triggering everything to moderation. They’ve now adjusted for that, and we haven’t seen it again.

TypePad AntiSpam is available now via plugins for Wordpress and Movable Type. Akismet has a much longer list of supported platforms - Six Apart says they will add more over time and, like Akismet, will rely on the developer community to pitch in as well.
