Mollom protects your site from spam, profanity, and unwanted posts. Focus on public and social engagement. Focus on things that matter.

Mollom protects your site from spam and unwanted posts. Mollom enables you to focus on quality content, and to embrace user-contributed content and public engagement.

Mollom automatically blocks all spam, accepts the content you want, and honestly admits when it is unsure — asking the author to solve a CAPTCHA. Obvious spam does not even enter your site; it's outright discarded instead. To learn more, check how Mollom works.

The Mollom service encompasses all spam filtering techniques that exist, using industry-leading content classification technologies that learn and automatically adapt, and is constantly monitored and improved by engineers — to allow you to focus on content: Quality content.

Mollom is actively used by more than 50,000 sites, including Sony, twitter, MIT, Adobe, Warner Bros Records, LinuxJournal, NBC, and many others. More than 4,500,000 posts are checked by Mollom per day.


  • Protects the comment form. (support for other core forms to follow soon)
  • Checks for spam and profanity.
  • Allows selected user roles to bypass the protection.
  • Integrates with WordPress' built-in comment moderation pages.

Do you have multiple WordPress and other sites that need moderation? Mollom's Content Moderation Platform is supported out of the box — Save time & moderate them all at once.

If you like Mollom, consider to write a review and blog about it! :)


To get the best performance out of Mollom, ensure to disable other spam filter plugins.
