What's working reasonably well is maintaining a cache with IP addresses in Cache::Cache, either in memory or on disc. If you find the IP in the cache, block the request. Experiment with the cache expiration setting.

This will be tough on requests from proxy farms (like AOL), because every request will look like its coming from the same IP, but for low-traffic sites, it's good enough.
