Is there some sort of code that doesn't allow a user to browse your website using a proxy? Trying to Google around to see, but thought I would post here in case someone already knows how. Thanks!
You could make a .htaccess file blocking the IP address of the site hosting the proxy. If you want to be creative, you can even redirect them someplace else. If you can't figure out how to block the IP address with a .htaccess file after making the effort to figure out how yourself using google, PM me and I will help you. Good Luck, -Justin
