The use of the Internet, including social media, by violent extremists and terrorists and their supporters has been a source of anxiety for policymakers and publics for a number of years. This is based on the idea that there is a connection between consumption of and networking around violent extremist and terrorist online content and adoption of extremist ideology (i.e. so-called ‘online radicalisation’) and/or recruitment into violent extremist or terrorist groups or movements and/or attack planning and preparation and/or, ultimately, engagement in violent extremism and terrorism. Concerns have been raised, in particular, regarding easy access to large volumes of potentially influencing violent extremist and terrorist content on prominent and heavily trafficked social media platforms.

Some scholars and others are sceptical of a significant role for the Internet in processes of violent radicalisation. There is increasing concern on the part of other scholars, and increasingly also policymakers and publics, that easy availability of violent extremist content online may have violent radicalising effects. This article identifies a number of core questions regarding the interaction of violent extremism and terrorism and the Internet, particularly social media, that have yet to be adequately addressed and supplies a series of six follow-up suggestions, flowing from these questions, for progressing research in this area. These suggestions relate to (1) widening the range of types of violent online extremism being studied beyond violent jihadis; (2) engaging in more comparative research, not just across ideologies, but also groups, countries, languages, and social media platforms; (3) deepening our analyses to include interviewing and virtual ethnographic approaches; (4) up-scaling or improving our capacity to undertake “big data” collection and analysis; (5) outreaching beyond terrorism studies to become acquainted with, for example, the Internet Studies literature and engaging in interdisciplinary research with, for example, computer scientists; and (6) paying more attention to gender as a factor in violent online extremism. This research was produced with the aid of VOX-Pol Research Mobility Programme funding and supervision by VOX-Pol colleagues at Dublin City University.

This article reflects on two core issues of human subjects’ research ethics and how they play out for online extremism and terrorism researchers. Medical research ethics, on which social science research ethics are based, centers the protection of research subjects, but what of the protection of researchers? Greater attention to researcher safety, including online security and privacy and mental and emotional wellbeing, is called for herein. Researching hostile or dangerous communities does not, on the other hand, exempt us from our responsibilities to protect our research subjects, which is generally ensured via informed consent. This is complicated in data-intensive research settings, especially with the former type of communities, however. Also grappled with in this article therefore are the pros and cons of waived consent and deception and the allied issue of prevention of harm to subjects in online extremism and terrorism research. The best path forward it is argued—besides talking through the diversity of ethical issues arising in online extremism and terrorism research and committing our thinking and decision-making around them to paper to a much greater extent than we have done to-date—may be development of ethics guidelines tailored to our sub-field.

This report treats developments in the violent extremist and terrorist online scene(s) and responses to them in the 13-month period from 1 December 2018 to 31 December 2019. It is divided into two parts: Part I focuses on the online activities of the extreme right, with a particular emphasis on the Christchurch attacks, and Part II on violent online jihadism, particularly the so-called ‘Islamic State’ (hereafter IS). The Conclusion provides a summing-up and identifies issues in this realm that bear watching in 2020. Those familiar with our previous reports will know that the structuring of these was slightly different, with analysis of violent jihadi activity preceding discussion of extreme right online activity in all instances. The March 2019 Christchurch attacks and a series of subsequent attacks in the United States and Germany put extreme right online activity firmly centre stage however, which is reflected in the structuring of the present report.
