My comments are down again. I need help!

Apparently the spambots are slamming my comment script so rapidly that Pair, my hosting service, keeps on disabling the script. That’s why comments aren’t working right now.

Anyone have any advice on dealing with this? I currently use Autoban (version 1.2.3), which is supposed to throttle any spambots that try to post zillions of time in a row. I’ve been using it for about a year now, with great success.

But something’s changed in the spambots’ behavior, I guess. Anyone with smart advice, feel free to email me — I’m all ears!
