One thing I don't understand is how you prove your from the EU. I route most of my internet traffic through various VPNs. I'm in the U.S., but am increasingly more often hit with EU specific guidence. Prove I'm from the EU (or US) - you can't.
Why would they need to prove that?
the EU says I owe them 10 trillion dollars. I have no assets in the EU. what next?
