Block users from certain sites

Hi, I was wondering: How do i block users from certain sites wanting to go to my site? Specifically I'm trying to block users from proxy.org

thanks

 

Block proxy.org's ip address through cpanel.

 

how do i find its ip address?

 

Just checked proxy.org, they use various other proxies rather than providing the service themselves. It would be hard to block all those proxies unless some one knows any other way of doing it.

 

Try domaintools.com, easy to use.

 

Write a script to pull the list of servers from proxy.org, reverse DNS the domain to get the IP(s) that the site is hosted on, then block those IPs. You can run a cron job to run the script daily.
