The best thing you can do is install the new version of blacklist. It completely solved my problem. It closes comments on all posts older than...whatever date you set. I opted for 14 days.

I went from getting hundreds a day to nothing...or one or two that get trapped in the moderated bin and don't show up on the blog.

Good suggestion, Paul. Pixy already set me up an MT3 playground, I just haven't had the time to get it ready for use yet. Guess I'll be making that a priority.

I was being *minimally* crapflooded over the weekend. Quite obviously I was pissed because I just moved off my old site because of comment spam.

I wanted to quit. Then I wanted to cry.

Then I decided to buck up and load the shotgun.

Do what I had Kittysays do, change your commenting to where you have to preview first, then post.

Use both of those links, they will help you modify your code to fix the spaming issue.

I did the forced preview thing. Our multi-blog setup makes the other one impossible. Hopefully this will at least slow the bastards down.

Yay preview. I'll have to see if I can set that up for Lemur Girl.

If you want to shift to MT3 then let me know and I'll have a squizz at the template changes you need to make.

I dont think mu crowd wants to do that. Personally I'm boycotting MT3.
