How to read it

An American Mobile Proxies line shows a US mobile carrier as the ISP, because the IP is from the carrier's pool and many real phones use it together through carrier-grade NAT. The location is the metro or the state, not the street. Two things make an account easy to spot: a browser time zone that is different from the IP, and a WebRTC candidate that shows your home or office address. Change these two in the browser profile, then do the check again.
