Checking your VPN exit location

Look up your current IP to confirm the VPN is routing through the country you selected. If it still shows your real location, the VPN isn't working.

Flagging suspicious sign-ups

A user claims to be in London but their IP resolves to a data centre in Eastern Europe. That's worth a second look before approving the account.

Understanding where an email came from
