[wp-hackers] Re: [spam-stopper] New plugin version

[Sebastian Herp]

Good idea ... I think it could be handled only by plugins, too ...

Anti-spam plugins would hook into preprocess_comment and do whatever 
check they do (against Akismet, a RBL, etc). They would have to save 
their result into some global array (the same one for all plugins 
dealing with spam). Then, in the pre_comment_approved hook the 
uber-anti-spam-plugin collects the values in this global array and 
decides whether it's spam or ham.

Needs no modification of the core ... or am I wrong?
