I need help!

Sigh – another 100 comment spams overnight. I can usually stop the one during the day by blacklisting immediately, but not much one can do when you wake up and they are all there.

I simply haven’t got the time to retrospectively delete so much spam, so may have to look at requiring registration system for comments. I would hate to turn off the comments all together, as I think they are the best part of the blog.

Does anyone know if there is a plugin for Movable Type that allows registration or better control of comments? If not, any recommendations on alternative software that I could petition supreme overlord Gordon to install?
