After several months of private beta testing, Benjamin Schrauwen and I are happy to unveil Mollom, your partner in automated content monitoring. Mollom's purpose is to dramatically reduce the effort of keeping your websites clean and the quality of their user-generated content high. Currently, Mollom is a spam-killing, one-two punch combination of a state-of-the-art spam filter and CAPTCHA server. We are experimenting with automated content quality assessments, but these are still in an early testing phase.
If you're interested in learning more about how Mollom works, check out the 'How Mollom works' page and visit the Mollom FAQs for more details.
