I haven't used Netflix in a few years so I don't know if it works the same now, but the region restrictions were based on your IP address, not credit card info or anything. That meant you could easily turn on a VPN and easily access the worldwide Netflix library. They would blacklist IPs from public VPNs like Private Internet Access, but you could easily just set up OpenVPN on a Linode to get around that.
