With comments broken most of the time, I don't expect to see a lot of comment spam but if this movable type throttle solution ends up being worse than the spam problem, I'm thinking about other ways to deal with spam floods. One thing I've been thinking about is just removing the "post" button and forcing everyone to go through "preview" which seems like it would cut down on a lot of the spam without too much hardship for commenters.
What do you all think. Do you have experience with spam floods at your weblog? Besides MT blacklist and throttling, are there other good solutions?
