Good luck.
So don’t say anything specific, like that you’re using a VPN. I use VPNs all the time, but when talking to my on-line broker, they were able to detect that I was using it, and told me to shut it off, so it’s too thin a ruse. VPNs are yesteryear’s technology, and the Federal Bureau of Instigation has ways of seeing through them. We need smoke signals, or carrier pigeons, or encryption methods that can’t be broken.
