"In fact, no country allows unrestricted flow on the Internet of pornographic, violent, gambling or superstitious content, or content on government subversion, ethnic separatism, religious extremism, racialism, terrorism and anti-foreign feelings."
No, some but certain countries figure they'll just censor anything thats unfit for their little "children." Last time I checked, you could buy the Anarchist Cookbook in the U.S., you just have to accept the fact that it look suspicious and will show up in records and such. But it's still publishable, and isn't hidden from society.
