This module gives you pre-moderation function for some comments that includes bad words or disallowed urls. Bad comments will have unpublished status and have to be approved manually on page 'admin/content/comment/approval'. All other comments will be published as usual.

If all comments already pre-moderated you don't need this module.

Configuration page at url: admin/settings/comment_control/ (d6) and admin/config/content/comment_control (d7).
You can edit list of allowed urls, disallowed words and bad words. The last list is separated for special purpose - not to hurt your eyes each time you edit configuration page :-)

Requires mbstring PHP extension.

Thanks to Abhijeet Sandil for Drupal 7 update.
