Tunisian bloggers collaborated on a mapping project that revealed the presidential plane was being used for extensive personal travel. Their campaign began when a blogger, Astrubal, discovered images of the Tunisian president's plane on websites devoted to tracking air traffic. Using this data, Astrubal combined the plane photos with a visualisation created using Google Earth to show which airports the plane had been seen at and when. The video spread on YouTube, which led to the mainstream media investigating further. As a result, the issue of misuse of public property by government officials received much attention, but as another consequence the Tunisian government blocked YouTube and another video sharing site, DailyMotion.
