Mollom vs Trackback spam

Hum. The plugin in WordPress doesn’t support trackback checking yet. No big deal? Well, I have 24 spams in my moderation queue, the majority of them are trackback spam.

So… yet another feature to implement. Just wondering how the flow of operations should look like. Moreover: how/where do I implement a CAPTCHA? Is it necessary to do this implement? Given the 99.8% accuracy Mollom claims, is it a bad thing if a trackback would be identified as a false positive and the CAPTCHA step is skipped altogether? One can retrieve the false positive through the moderation queue altogheter, no?

Anyway, adding trackback support should be fairly simple.
