This plugin will scan new registrations at your forum and it will block registrations made through/beyond regular open proxy ports 80 and 443.
Not all proxy servers are guaranteed to be blocked as there is no such thing as a 100% proxy block. It stops access by many of the most popular proxies (such as Hide My Ass and Tor Browser)
Another thing to note is that some universities, libraries, companies and countries might access the web through a gateway proxy, so they will be blocked from using your forums.
It may also prevent access to some AOL users.
White Proxies Exclusion:
The plugin comes with a setting to exclude specific proxy servers from being blocked based on their remote IP addresses (Whitelist).
