How Does Mollom Work?Mollom has been developed as a webservice that organizations can integrate into their content management sites. Basically any site that allows a visitor to post or contribute comments, forum posts or fill in contact us forms would use this service to ensure those comments are really not spam. The data to be checked is sent to Mollom.com which then reviews the content and returns a spam or ham classification response. In some instances, if Mollom isn't sure about the content, they return an "unsure" classification along with a prompt ask Mollom's CAPTCHA server to present the user with an audio or visual CAPTCHA challenge.
For those of you who have never heard the term, CAPTCHA is a type of challenge-response test that ensures a user is indeed a user and not a computer trying to spam a website. An example of a CAPTCHA test is shown below:
A key feature of Mollom is it's ability to store reported comment spam from participating sites that has "slipped through the cracks". This information is then used by Mollom to help it learn and prevent future abuse. Some other technical features of Mollom include: * Elimination of spam moderation queues * Extensive statistics - you can see realtime statistics on Mollom's homepage and also have an individual stats page for your site * Open API - Drupal users can use a pre-built plug-in for their CMS, everyone else needs to create their own plug-in using the API * Support for OpenID Content Quality Assessment from Mollom Another enhancement for Mollom is the Content quality assessment currently in BETA. These are automated content quality assessments where Mollom will provide a quality score for each post it receives. Your site can ignore or reject comments marked as spam by assessing the score for the post. This gives the website owner the ability to control comments to site based on their own metrics rules.
