mod_refererblacklist?

My poor server took a hammering today, when some referer-spamming shitbag hammered MovableType’s comments CGI script, effectively DDOSing it.

I chucked in some mod_rewrite rules to try to make this a little less likely in the future, but here’s a Lazyweb request:

Any ideas on a way to take the Comment Spam master blacklist and use it at an Apache level to block requests having a Referer that matches? Preferably one which doesn’t use more CPU cycles than the spam attack I’m looking to solve!
