During the second half on nineties net activist had no fear of censorship because they believed in the power of alternative internet routing and grassroots connections. Nowadays the challenge for an effective censorship has already been won by many states with China leading them for innovation and efficiency. Ten OpenNet Initiative (ONI) researchers were involved in this seminal report for a few years, focusing on general internet filtering strategies and motivations, and analyzing the filtering conditions and legal/ethical tactics state by state. Blocking content on the net is not only a very serious business, but also a subtle one, extremely diversified. Every sensitive country has its own mix of motivations and consequent strategies. So, showing a warning or a disguising error web page is a political choice, directly reflecting the government policies, as well as using passwords, IP classes or entire services (Skype) as the censorship technical targets. Scanning the different filtering politics is like viewing a social and political atlas, revealing what a formal territory fear most. And the resulting patterns constitute a contemporary geography of mute networks.
