You can't take down sites that are not within your borders or TLD, and if they don't cooperate. Also, something can be illegal in a place, but not in some other place. So the country where something is hosted can just apply their law. For a long time, torrent websites have been hosted in Sweden, for exemple, where they were fully legal. As long as they don't break laws in Sweden, they're fine. In the same fashion, China can't take down the sites it finds illegal at home. The UK will never take down felons at "BBC.com". China can only block them through the GFC
