Luur VPN Checker
Luur VPN Checker is a skript that allows server owners & staff to block users that use VPNs & Proxies.

Why Luur?
I have been browsing all the four corners of the internet (no I am not a flat earther), to see if anyone has made an up to date VPN checker for skript because I wanted to use one for my server, and I realised that the last one that was ever updated to any kind of degree was back in 2018 so I decided to release this to the skript communty.

How does Luur work?
Luur uses an external API called proxycheck.io to query the IP the user is joining with and it responds with a lot of information on the ip address. If it reponds with a VPN for the type of IP it is it will log and kick the user
and do it for all of the proxy types such as OpenVPN, SOCKS, SOCKS4, SOCKS5, TOR, Shadowsocks, HTTP, HTTPS, Compromised Server, VPN, or Inference Engine. However if the IP bypasses these checks another API is used to check it just incase.

I will be testing more VPN & Proxy software in the future to improve this skript even more, but for that to happen I need people with VPN & Proxy software willing to help me develop this skript.

Requirements

Skript [v2.2-dev25+] (For the skript's functionality)
SkQuery [v3.2.1+] (For the skript's functionality)
SkriptJSON [1.0.0+] (To pick out key parts of the API response)
json.sk [2.3+] (Required for the cool messages in /luur help) (In version v0.5)

Stats for the nerds

The first check blocks NordVPN with 96% accuracy and the second check covers the other 4% so in total NordVPN is 100% detectable. (Data is from 49 seperate tests)

Now blocking over 74.3million unique IP addresses and 40 VPNs
