new social media filtering maps from the opennet initiative

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.

If you’ve been having a hard time keeping track of whether Twitter is accessible in Tehran or if Fallujah is blocked Facebook, you’re not alone. Luckily, I just completed a project for the OpenNet Initiative to help you out.

Based on testing conducted in 2008-2009, ONI 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.

Visit them now, and lay your social media filtering questions to rest.
