There is a growing body of evidence that terrorists/terrorist groups have increased their use of the Internet to include a move into online social network environments in their efforts to radicalise and potentially recruit and mobilise new members. Both the US and UK governments acknowledge that not enough is known about this phenomenon and there is an urgent need for more substantive research in the area of terrorists’ use of computer-mediated communication. However, research in this area carries with it some serious ethical and legal concerns that cannot and should not be ignored. UK law makes it difficult for terrorism studies researchers and other academics to conduct this online research without potentially violating the law. With careful consideration of the ethical concerns surrounding the methods of data collection, and knowledge of and adherence to Data Protection laws, along with notification of proposed research to the proper law enforcement office to insure compliance with the UK Terrorism Act, it is however possible to move forward with academic integrity and a reasonable assurance that one will not be charged and prosecuted for violations of the Terrorism Acts.

This thesis examines why approximately 700 German foreign fighters traveled to Syria and Iraq between early 2012 and late 2015. It presents the author’s original research on 99 German foreign fighter profiles, examining their preexisting network connections in Germany as well as their biographical availability and integration into German society. The study finds that German foreign fighters are primarily mobilized through traditional social network connections and that the mobilizing network in Germany consists of a nationwide, interconnected, and politically active “Salafist scene.” The project also finds that while Western governments often worry about the looming threat of online radicalization, verifiable examples of purely Internet-based radicalization remain rare.

The last half century has witnessed a burgeoning information revolution that has transformed our societies beyond recognition. The development of sophisticated computing, the technological reorientation of vast segments of the global workforce, the invention of the internet and most recently the proliferation of social media technology has radically changed the ways we work, live, develop and communicate. Political extremism and violent radicalism have not been excluded from this growing trend, with social media being used as a tool for the recruitment and exploitation of young people by extremist groups.

As a result, the development of digital citizenship in our young people, to help them navigate these new online challenges, has become an urgent need. British schools are responsible for identifying and building resilience against radicalisation as part of their duty of care. Many of the skills required to combat the influence of extremism and the ability of terrorist groups to exploit and manipulate young people are already taught in schools, through existing personal, social, health and economic (PSHE) education and citizenship efforts, the British values agenda and the work of individual school leaders and teachers. However, there is a dearth of high-quality resources designed to increase the resilience of young people to extremism and radicalisation in a digital context.

This report summarises the results of a pilot project which seeks to address this gap by developing, testing and evaluating new resources to help schools tackle online radicalisation. Based on the analysis of a survey of existing materials and a best practise review, it presents a digital citizenship intervention, developed by Demos and Bold Creative, designed to build this resilience to extremism, and measures its impact through a pilot study delivered in schools. At a time when the growth of social media combined with the influence of extremism makes it more important than ever, this report adds to the public evidence base regarding counter-extremism interventions in a school context, and contributes to the development of effective education for digital citizens.

Online extremism has changed, and censorship by content removal or account suspension alone cannot counteract it. We need a radical new response, argues Louis Reynolds.

This article investigates Twitter data related to the kidnapping case of two German nationals in the southern region of the Philippines by the Abu Sayyaf Group (ASG). It explores perceptions of the ASG, along with associated organizations and sentiments indicated in the tweets together with statistically significant relationships. Findings revealed that: “Rebel” and “Militant” were the most frequently used labels for the ASG; a majority of the tweets contained sentiments that assess threats such as abduction and kidnapping of hostages; and almost half contained words that indicate negotiation or concession to the demands of the captors. Logistic regression analyses on “Rebel” and “Islamist” revealed positive coefficients for these sentiments used as predictors. This meant that people who assessed threats and expressed sentiments that responders should concede to the captors’ demands were more likely to use the “Rebel” or “Islamist” labels. Rather than the two longstanding dominant narratives of the ASG as terrorists and criminals, the emerging rebel and militant labels suggest a more domestically and politically sensitive Twitter commentary than is represented in the work of the Al-Qaeda-centric paradigm exponents. These findings, along with the complex associated political and policy contexts and implications, are discussed in this article.

The prevalence of dangerous misinformation and extreme views online has intensified since the onset of Israel-Hamas war on 7 October 2023. Social media platforms have long grappled with the challenge of providing effective mitigation schemes that can scale to the 5 billion-strong online population. Here, we introduce a novel solution grounded in online network engineering and demonstrate its potential through small pilot studies. We begin by outlining the characteristics of the online social network infrastructure that have rendered previous approaches to mitigating extremes ineffective. We then present our new online engineering scheme and explain how it circumvents these issues. The efficacy of this scheme is demonstrated through a pilot empirical study, which reveals that automatically assembling groups of users online with diverse opinions, guided by a map of the online social media infrastructure, and facilitating their anonymous interactions, can lead to a softening of extreme views. We then employ computer simulations to explore the potential for implementing this scheme online at scale and in an automated manner, without necessitating the contentious removal of specific communities, imposing censorship, relying on preventative messaging, or requiring consensus within the online groups. These pilot studies provide preliminary insights into the effectiveness and feasibility of this approach in online social media settings.
