Ordinary people use the networks to provide others with a window into their lives and their experiences. The networks are also often used as propaganda tools by opposing groups in a conflict. In addition to uploading photographs and videos to these sites, these groups also have narratives on events that could provide valuable information. For example, the Facebook page of an armed opposition group posted a photograph of a government soldier it had captured. It provided details such as the soldier’s name, the date and place of his capture. Further images showed the soldier being beaten, with an explanation that he was beaten because he refused to provide information about government troops in the area. A few days later a picture of the same soldier, now dead, was posted on the Facebook page with a warning that this would be the fate of captured soldiers who refused to provide information. 48 COMMISSIONS OF INQUIRY AND FACT-FINDING MISSIONS ON INTERNATIONAL HUMAN RIGHTS AND HUMANITARIAN LAW
