I came across this service a little earlier in the week and can’t wait to give it a try! It is quite possibly the first real competitor to Akismet for community spam filtering and control. The Drupal community is all up in arms with praise for the beta-service.
Sometime next week I think I’ll toss it onto one of my Drupal sites and see how it does for a while. While I’ve been pretty happy with Akismet (which I use on this site), competition is always a good thing and everyone likes to detect and delete spam.
What appears to be the claim to fame with Mollom is that learns from it’s mistakes and your content. Apparently one of the features in the pipe is content filtering, like nuking inappropriate language from community sites. While the community sites that I’ve managed haven’t had much of a language problem, those things do happen and varying defense levels certainly help to quell managerial fear.
