Website comments are turned off

I noticed yesterday that we wre starting to get a number of comments regarding specific pages on the website so I went looking to see what I could find. What it turned out to be was someone who found the site made comments on every page that he could get to promoting porn websites. After cleaning that mess up I've turned off comments on articles and news. While this should prevent this from taking place again it does take away a part of the new website that I really would like to get back. The only possible option that I see right now is to set things up so that you would need to register to view the comments just like you currently do to post to the forums. But for now I'll just leave comments turned off.
