Six Apart has launched TypePad AntiSpam, available for both Movable Type and WordPress this open source software hopes to combat all your spam problems.

Being open source, including the back-end must be a worry to potential users, as its main competitor Akismet is not open source and has proved a success for the most part. However we are promised there are parts which are not exposed  which could allow the system to become compromised by spammers.

“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.”

The self learning system has already been adopted by the likes of ProBlogger who recently asked his readers to report any problems, and as of writing this there seemed to be very little. Time will tell, having an alternative option is always a necessity with software. This blog will however be sticking to a proven winner – Akismet, who has of today prevented 30,151 pieces of spam.
