4. Cookies for Comment

This anti-spam plugin takes a different approach. It sets a cookie on a random URL that is then checked when a comment is posted. If the cookie is missing the comment is marked as spam.

So if a spambot leaves a comment the cookie is checked, if it doesn’t exist the comment is marked as spam.
