Jay Allen has come up with version 1.5 of MT-Blacklist to combat spam in comments and trackback. I have installed the new version and it works great. No more errors that I got with version 1.0beta and no slowing down of the rebuild process.
I haven’t been getting too much spam in my comments, but there are a few every week. It’s just been a small nuisance to delete those comments. Hopefully, this will fix the problem before it gets too big for me.
My blacklist is here.
