Yes, that would be fine, as it would be here.
What I have a problem with is nations saying that a site built and hosted in a totally different country with a different set of laws and norms is “illegal” globally. Yes, I don’t like it when the US goes after people like The Pirate Bay abroad either, but that’s a result of the US being able to bully other countries for whatever reason it wants to. (That also needs to change.)
If Europe or the UK wants to protect its citizens, it should either block websites that it sees as a threat (as most of the EU does with RT) or it should come up with a scheme where ad networks with nexus in the EU must stop doing business with them. Attempting to reach across borders into the US to change US domestic norms is going to get them a well-deserved slap in the face.
