Not web sites. Service providers. They mean ISPs. They aren’t holding pornhub liable if you use a VPN and are located in Utah.

The law is also technically flawed, given that it assumes that a web provider can reliably detect VPN traffic and determine a user’s true physical location — they can’t. IP reputation databases such as MaxMind and IP2Proxy can flag traffic from known datacenter IP ranges, but commercial VPN providers rotate addresses constantly, and residential VPN endpoints are largely indistinguishable from standard home connections. Autonomous System Number analysis can catch traffic originating from datacenter networks, but can’t identify a personal WireGuard tunnel running on a cloud VPS, for example, which routes through the same infrastructure as ordinary web hosting.
