> “VPNhub is free and unlimited, anonymous and easy to use, [...] a good number of [people] use [VPNs] to circumvent and bypass restrictions to access adult content. It only makes sense that they use Pornhub’s.” So wait, as a UK citizen I can use Pornhub's VPN to circumvent the UK Government's "Porn Filter", a system that's run by..... Pornhub.
The system was mandated by UK law. Mindgeek isn't the only provider that makes an age verification service, though they are the largest (since they own most of the largest pornographic brands on the web).
David Cameron was the one who pushed for the law that put all of this into effect; Pornhub isn't remotely responsible. They're just creating a verification service that they're now legally required to run to comply with the law.
