The totalitarian regime in mainland China have an internet filter to block from it citizens anything not to the liking of the regime. It by a large measure is successful only because of the thousands employed to maintain it (good for employment). However I have occasion to communicate with some of those citizens via online means that the net provides and it does not stop me from passing on to them anything I like. Perhaps the only way to get an effective filter is to get the G20 together and develop a world wide one. That would surely spur economic activity to an extent that would bring the world out of the currently slump.
