Experts argue that the internet has provided expanded opportunities for violent extremist groups to propagandize and recruit. The Islamic State of Iraq and Syria, or ISIS, is an exemplar in that it has heavily invested in an online presence and uses online communities and social media to attract and retain supporters. Does ISIS’s online presence translate into a higher probability that individuals in its target audience will become supporters? In this study, we analyze over 6,000 individuals in six Arab countries to find if those that use the internet to follow political news or to express political views are more likely to support ISIS. We find that respondents who get their news online are significantly more likely to support ISIS than those who follow the news on television or print media. Moreover, those who use online fora for political expression are also more likely to express support for ISIS. Indeed, individuals who engage in online political discussion are more likely to support ISIS than those who engage in conventional political activity, though less than those who engage in contentious political behaviors such as attending a political protest. We conclude with a brief discussion of the academic and policy implications of these findings.

While the extreme right wing (ERW) has not gained a foothold in local or national Irish politics, the country has witnessed a growth in online activism and harassment, and physical protest and violence. This paper explores a case study based on 4876 unique posts from one Irish-based Telegram group active during six months of the COVID-19 pandemic. The main findings are that: (a) this group was heavily influenced by foreign content and influencers, in particular, American ERW content and conspiracies associated with QAnon; (b) conspiracy theories were not adopted wholesale but adapted for an Irish audience; (c) Irish actors were not passive receivers of US content, and multi-directional exchanges of ideas were witnessed. While generalising beyond the case study analysed in this paper would require further data, this may suggest that Irish influencers are part of a transnational online ecosystem in which ideas and theories are shared and adapted to local contexts. These findings offer insights into the ERW in Ireland and, more generally, how the ERW communicates and spread conspiracy theories across national borders.

In this Perspective, the authors introduce a framework for internet users to categorize the virtual platforms they use and to understand the likelihood that they may encounter extreme content online. The authors first provide a landscape of the online extremist “ecosystem,” describing how the proliferation of messaging forums, social media networks, and other virtual community platforms has coincided with an increase in extremist online activity. Next, they present a framework to describe and categorize the platforms that host varying amounts of extreme content as mainstream, fringe, or niche. Mainstream platforms are those for which only a small portion of the content would be considered inappropriate or extreme speech. Fringe platforms are those that host a mix of mainstream and extreme content—and where a user might readily come across extreme content that is coded or obscured to disguise its violent or racist underpinning. Niche platforms are those that openly and purposefully cater to an extreme audience.

Online radical Islam is a topic widely studied by scholars and notoriously discussed among non- experts as well (; ; ). Because of its intrinsic characteristics (i.e. accessibility, anonymity, or users’ identity dissimulation), the internet has always been a useful tool for propagandists of Islamic fundamentalism (; ; ). However, in the last decade, studies have questioned the real importance and magnitude of Islamic radicalization online (). In fact, while scholars were focused on observing digital Islamic radicalization, a galaxy of new forms of extremism was growing online (; ) that no longer made Islam an exceptional case study. Today, Muslim people are one of the groups most aggressively targeted by extremist, intolerant, violent, and radical discourses (; Amnesty International, ). Anti-Muslim hate speech has spread online throughout Europe and the United States, reinforced by the propaganda and political discourse of populist right-wing parties (; ). This paper introduces some large-scale action-research projects developed in Europe and Italy in the last three years (2016–2019) and aims to reconstruct the most updated Islamophobia state of the art in terms of numbers, characteristics, and phenomenology from the offline to the online context.
