Preventing spam

User comments are some of the best content that you have on your site as far as the search engines are concerned. They reinforce the ideas already on the page and the best thing of all is that you didn't need to lift a finger for someone to add value to your web site.

However, user comments introduce a whole set of problems called Comment Spam. Just because you have a web site, some users will use it as their own little playground for creating links back to anywhere they want. Fortunately, there is a terrific, and mostly automatic, service for preventing spam called Mollom. Mollom was created by Benjamin Schrauwen and Dries Buytuart (Recognize that name? He's the founder of Drupal!). Thanks guys, you've got a winner here!
