Spambam beta test

I've worked on a new version of Spambam which has a lot more features, it now doesn't reject spam but simply moves it into a spam folder. I'd be interested in what everyone thinks about it and if this method is preferred to simply blocking all spam. The reason behind the method change was to stop valid comments from being rejected and give the ability to restore comments which are marked as spam.

The beta can be found here (Spambam is now part of Blogsecurity):- Spambam beta
