To Block Spam: ReverseDOS
I read about it quite a bit, and after tha last round of trackback spams, which dasBlog still doesn't handle, I decided to give it a try. The webseite is very clear, and the installation is a piece of cake. Drop the file in the bin folder, add some lines in Web.Config, and you're done.
The nice thing about it is that it should stop a wide range spams (comments, CommentAPI, refferers, trackbacks) using a single tool and without modifying the application at all. It's like Ascpecting the application.
If you've a blog and want to reduce spam, check it out.
