If you login with a VPN, it can happen. It doesn't always happen. It depends on the server. I would assume that if you do violate their content restriction, they would in fact end your membership.
Of course they had no problem with vpn use until a couple of years ago. Why do you think that is?
Probably because people using PROXY servers to view content they have not compensated content creators for viewership in end users countries wasn't an issue until a couple of years ago.
No that's not even close to being it, but you go with that...
