JM Berger outlines a useful theory of how Islamic State uses twitter to indoctrinate potential recruits. This theory is useful for all forms of social media propaganda. Find it at Combating Terrorism Center


“Abstract: The Islamic State has devoted significant resources to implementing a distinct online recruitment strategy, which follows targets from their introduction to the organization’s message, through a careful pruning of their social networks, before culminating in a call to action. The strategy relies on scores of users who maintain a high level of availability online, allowing them to lavish attention on potential recruits, and who provide a drumbeat of incitement to action, such as social media activism, migration to Islamic State territories, or the commission of terrorist attacks.”
