The warning module for Drupal that I blogged about earlier is now available from the drupal.org website at:

http://drupal.org/project/warning

Try it out, it helped to decrease my comment spam without needing any drastic actions (like closing comments on older articles) and early feedback from testers proofs promising.

Let me know what you would improve !

Next up is adding the comment_moderation module as well so it becomes easier to manage your comments on moderated sites.
