ProxGFY Features:

• Block all non-elite proxies from accessing the site.
  
• Block all TOR traffic from accessing the site.
  
• Block specific IPs from accessing the site.
  
• Block specific VPNs from accessing the site.
  

How this works:

• All non-elite proxies will announce their proxy status to the server so that's easy to filter out.
  
• All TOR addresses are public, so that's easy to filter out as well.
  
• Filtering out elite proxies requires manual additions to the blacklist.
  
• Filtering out VPNs requires ASN data which includes subnet ranges.
  

Upcoming Features:

• Include elite proxy blacklist.
  
• Include anonymized email blacklist.
  

Installation:
Just simply copy and paste the proxgfy.php and proxgfy folder into your inc/plugins folder. Once you've done that, you can then head to your ACP and enable the ProxGFY plugin.
