Blog Comment Spam Idea

If you have a blog at some point you have received comment spam. If you are using MovableType chances are you have experimented with the MT-Blacklist plugin. MT-Blacklist allows blog authors to mark comments as spam, and share their findings with the larger community, so everyone using the MT-Blacklist can block the same comments automatically.
Great project idea… start parsing the information provided by MT-Blacklist to create rulesets to block email spam? Chances are there would be some overlap don’t you think?
