Sure, its cheap and easy. Plus you know those UK users will just get a VPN and come anyway so you don't lose a thing. Its only 4chan that wants to make this public. They don't have much in the way of advertising revenue so there isn't much damage that can be done to them. Either way, the actions of the UK government are largely irrelevant again.

If the UK government bans VPNs, now they have more people in jail for speech violations than Russia and a more restricted Internet than China. The jokes write themselves at that point. It also becomes a virtue to dunk on the UK government worldwide. All to keep people from reading a site that the majority of people have no interest in. Its sad really...
