[squid-users] Blocking access to external proxies

I have detected some accesses to external proxies.
These accesses are being used to void squid controls and navigate without
controls, sometimes anonymously.

I believe that is almost impossible to know all server names to block them
individually, just to have an idea Google found hundred of pages with proxy
anonymous keywords.

Can I block these access with some ACL definition? How can I do that?

Thanks and Regards.
