What is the best way to block public proxies? Is there a good source that is updated on a regular basis? My next question is sites like Hidemyass that have private virutual ips, is there a good way to block them? We have a small and growing site and need a way to block public ip's. We are starting to get stalkers and trolls on our server and have had little luck stopping them because they are hiding behide the cloak of public ips. Any ideas or suggestions would be appreciated.
