Title: The Conceptualisation of Extremism Online

Outline: The rise of the online environment has been a game changer in enabling extremist movements to destabilize civil societies around the globe. This presentation explores the interface between extremism and the internet and presents contemporary approaches to understanding violent extremism online.

The so-called ‘alt-right’ is an amorphous but synchronized collection of far-right people and movements, an umbrella label for a number of loosely affiliated social movements around the world, although its centre of gravity is in the United States. Many factors have contributed to the alt-right’s rise to prominence, but one of the most visible is its online presence. Alt-right views have been promoted online by a small army of trolls and activists staging harassment campaigns, pushing hashtags and posting links to extremist content and conspiracy theories on social media. Since 2016, the alt-right and its allies have held an increasingly prominent place in American and European politics, rallying support behind a variety of causes and candidates. This study seeks to evaluate the alt-right’s online presence with robust metrics and an analysis of content shared by adherents. The alt-right has many components online; this report will primarily examine its presence on Twitter, in part because the movement is particularly active on that platform, and in part because Twitter’s data access policies allow for more robust evaluation than is possible on other platforms.

Erratum: Due to a collection error discovered after publication, some tweets in this dataset were truncated. This mainly affected the precise counts of top hashtags and may also have had a minor impact on the order in which hashtags were ranked. We do not believe the impact is material to the study’s overall findings.

Policymakers and scholars fear that the Internet has increased the ability of transnational terrorists, like al Qaeda, to attack targets in the West, even in the face of increased policing and military efforts. Although access to the Internet has increased across the globe, there has been no corresponding increase in completed transnational terrorist attacks. This analysis examines the causal logics—which have led to the conventional wisdom—and demonstrates both theoretically and empirically that the Internet is not a force multiplier for transnational terrorist organizations. Far from being at a disadvantage on the Internet, state security organs actually gain at least as much utility from the Internet as terrorist groups do, meaning that at worst the Internet leaves the state in the same position vis-a`-vis terrorist campaigns as it was prior to the Internet.

The Islamic State of Iraq and ash-Sham (ISIS) continues to use social media as an essential element of its campaign to motivate support. On Twitter, ISIS’ unique ability to leverage unaffiliated sympathizers that simply retweet propaganda has been identified as a primary mechanism in their success in motivating both recruitment and “lone wolf” attacks. The present work explores a large community of Twitter users whose activity supports ISIS propaganda diffusion in varying degrees. Within this ISIS supporting community, we observe a diverse range of actor types, including fighters, propagandists, recruiters, religious scholars, and unaffiliated sympathizers. The interaction between these users offers unique insight into the people and narratives critical to ISIS’ sustainment. In their entirety, we refer to this diverse set of users as an online extremist community or OEC. We present Iterative Vertex Clustering and Classification (IVCC), a scalable analytic approach for OEC detection in annotated heterogeneous networks, and provide an illustrative case study of an online community of over 22,000 Twitter users whose online behavior directly advocates support for ISIS or contibutes to the group’s propaganda dissemination through retweets.
