It is relatively easy to identify tens of thousands of social media users who have an interest in violent ideologies, but very difficult to figure out which users are worth watching. For students of extremist movements and those working to counter violent extremism online, deciphering the signal amid the noise can prove incredibly daunting. This paper sets out a first step in solving that problem. The authors have devised a scoring system to find out which social media accounts within a specific extremist circle were most influential and most prone to be influenced (a tendency we called exposure).
