> Who defines what is harmful or extremist in the government?

An additional related question: Are they even capable of undertaking this task? Our current government officials and bureaucrats don't understand enough about how the Internet works to effectively police it. And more fundamentally, can a government act quickly enough to outwit how quickly the Internet adapts to roadblocks? Governments need to have policies, procedures, go through chains of command, etc. A lot of Internet culture, on the other hand, is driven by random people doing random things. If a topic is forbidden, instead of policing that topic, the government then has to police the 50 ways to get around the block as well as guess which one will take root.

It's similar to trying to win a war against guerrilla insurgents. The high level of organization of a government to some degree works against them.
