Live proxy and VPN detection

Aside from simple detection, being able to _identify_ private relay is kind of a fundamental required feature for a tool like this, because the utility of identifying proxy/vpn traffic is destroyed if you’re going to lump “everyone with an apple device” into the pool

On Private Internet Access VPN:

* Proxy Score: 45/100 - Likely a Proxy

* VPN Score: 10/55 - Could be a VPN (But Unlikely)

ok but how does this work? i was expecting atleast a paragraph on HN to be honest

The documentation page linked to the demo page gives a good explanation on how this works (https://proxy.incolumitas.com/integration_instructions.html)

> The most important proxy detection tests with the highest accuracy are:

The reason why this test is effective: It is very hard to spoof and fake the latency test effectively. Furthermore, this test captures the very essence of proxy connections.
