Joey has implemented blogspam support for ikiwiki, which you can find here.
He was also good enough to provide valuable & useful feedback so I can present a moderately updated API - most notably with the ability to train comments when/if they are incorrectly marked.
I can imagine several other useful additions, but mostly I think the code should be cleaned up (written in an evening, posted to keep myself honest, didn't really expect anybody to be terribly interested) and then it should just tick over until comment submitters adapt and improve to the extent that my sites suffer again ..
