How about sign up for something called CloudFlare (http://www.cloudflare.com/)?

It is a content distribution network (CDN) designed to improve site
up-time, reduce bandwidth and also stop spammers.

I think it works something like this: Spammers have certain network
patterns. If other sites in the CDN identify those spammers, then
their patterns can be recognized and other sites in the CDN will be
protected. The service is free since everybody in the CDN benefits
from more participants.

I have not used it, but it is worth looking into.
