How Accurate Is a Proxy Detector in Identifying Fake IPs? or Can a Proxy Detector Really Spot All VPN

Honestly, most proxy detectors are trash. They either miss the obvious or block grandma for using her home WiFi.

I’ve been testing ProxyCheck.io lately, and it’s surprisingly decent. Their API is fast, and they have a free tier if you wanna poke around.

Biggest plus? They don’t just rely on IP lists—they actually check for open ports and other proxy behavior.
