ONI Presents Social Media Filtering Maps

The summer of 2009 was a hectic one for online social media: Twitter, Facebook, YouTube and a bevy of other sites fell under the censors' axe in China and Iran as political events - namely the anniversary of the Tiananmen Square massacre and the Iranian presidential election - shook both countries. Based on testing conducted in 2008-2009, the OpenNet Initiative has compiled data on the most frequently blocked social media sites around the world. We are proud to present five new social media filtering maps that serve as easy visual guides to the countries where Facebook, Flickr, Orkut, Twitter and YouTube are blocked.
