Psychological theories of mobilization tend to focus on explaining people’s motivations for action, rather than mobilization (“activation”) processes. To investigate the online behaviors associated with mobilization, we compared the online communications data of 26 people who subsequently mobilized to right-wing extremist action and 48 people who held similar extremist views but did not mobilize (N = 119,473 social media posts). In a three-part analysis, involving content analysis (Part 1), topic modeling (Part 2), and machine learning (Part 3), we showed that communicating ideological or hateful content was not related to mobilization, but rather mobilization was positively related to talking about violent action, operational planning, and logistics. Our findings imply that to explain mobilization to extremist action, rather than the motivations for action, theories of collective action should extend beyond how individuals express grievances and anger, to how they equip themselves with the “know-how” and capability to act.

Social media and terrorist financing (SMTF) refers to how terror organisations (TO), sometimes called violent extremist organisations (VEOs), have exploited free social media platforms to raise money for terrorism/fighting/jihad, to recruit, train, equip, and transport fighters, to support extremist religious proto-states (e.g., Islamic State of Iraq and Syria [ISIS]), to market/brand an organisation including to disseminate its ideologies, and/or to amass wealth. This chapter considers the scope of SMTF and legal/policy responses to its ever-evolving practices, discusses how it is practised and by whom, and considers the challenges of fighting SMTF. SMTF is part of the larger concept of cyberterrorism where terrorists target computer systems maliciously and use digital technology to facilitate terror attacks, though some argue that these two actions are completely different phenomena. The chapter concludes by summarising the key points of the discussion, offering suggestions for future study of this phenomenon, and reflecting on the societal impacts of SMTF.

It has become a familiar observation that social media usage can afford material assistance to the advancement of violent extremist or terrorist causes and can be a tool for counter-extremism and counter-terrorism efforts. This chapter discusses how several core supporting pillars of extremism mesh with social media in apparently similar ways to non-extremist activity and then considers the limited available literature on non-extremist online fundraising, moving thereafter to the literature which is more focused specifically on the study of social media funding for extremist or terrorist causes. It highlights the potential role of symbolic representation of shared values on social media and how this can help to address the challenges of an era where large-scale but ostensibly non-extremist movements such as QAnon and Stop the Steal arguably share some values in common with extremist causes and hence are a potential funding reservoir not necessarily observed if one focuses on specific extremist messaging content or extremist symbology.

The nature of terrorism financing has evolved with the exponential development and expansion of the internet. This dimension of terrorism funding has become a critical source for terrorist organisational mobilisation. The cyber funding of terrorism has coincided with the remarkable technological progress that has been achieved in the last few decades. This chapter provides a general background to the development of cyber terrorism funding. Then, it introduces relevant areas surrounding the cyber dimensions of terrorism financing that are currently challenging scholars, experts, and policymakers alike, including discussions on social media, cryptocurrencies, and the dark web. The chapter then discusses some technological tools and initiatives needed to counter the evolving nature of cyber terrorism funding through artificial intelligence techniques and protocols. Finally, it concludes with a discussion on future challenges. One potential tool that can aid in preventing terrorism funding is the utilisation of artificial intelligence.

Using a large, national survey of online Australians, we measured unintentional and intentional exposure to fringe or radical content and groups online. Two in five respondents (40.6%) reported being exposed to material they described as fringe, unorthodox or radical. One-quarter of these respondents (23.2%) accessed the content intentionally. One-third (29.9%) said the content they had seen depicted violence. Fringe or radical content was often accessed through messages, discussions and posts online. Mainstream social media and messaging platforms were the platforms most frequently used to share fringe or radical content. Being a member of a group promoting fringe or radical content was associated with increased sharing of that content with other internet users. Efforts to restrict access to radical content and groups online, especially on mainstream platforms, may help reduce intentional and unintentional exposure to and sharing of that content.
