But what's this MEDUSA's TENTACLES program meant to be? An artificial intelligence modelled on the personality of LD? <yeegawdz!>

It's a Detweiler Detector(tm) :-) It's a fuzzy logic database that keeps track of a user's posts and does stats on it. Afterwards, once a database is established, an anonymous, unknown post can be fed to Medusa. It will see how well the message matches to the poster's past spam.
