I have a major problem on my website. I have this one annoying person who keeps on flaming me. He changes his IP constantly so I can't block him by IP. What I would like to be able to do is block his email address since he seems to be using the same one to comment with. I have tried adding his email to the URL and URL Regex fields, but neither seem to block him. Is there a way I can set this up in Spam Karma or another plugin I could use along side to do this. I really need to be able to block this guy. He's getting out of hand.
