Six Apart has announced that it’s making the technology behind TypePad’s blog comment spam system freely available to bloggers using Movable Type 3/4, WordPress 2.5, or “any other platform which supports spam plugins”. The system is already built in to TypePad.
The beta version of TypePad AntiSpam is now available to both personal and commercial users, regardless of how many comments their blogs receive. It’s a self-learning system, meaning that whenever a user reports a comment as spam, the system should learn from that, and improve its spam filters.
As a potential rival to Akismet, TypePad AntiSpam is also fully compatible with its API.
As for concerns that open sourcing the system will simply aid spammers wishing to circumvent the system, the FAQ explains: “We aren’t sharing all of the rules and logic that we run with our implementation of the TypePad AntiSpam engine. We are open sourcing the core engine, allowing others to build on top of our system allowing them to build and operate their own spam service.”
An enterprise-class service may be offered in the future, along with a customised service for users with specific requirements.
