Little is known about online behaviours of violent extremists generally or differences compared to non-violent extremists who share ideological beliefs. Even less is known about desistance from posting behaviour. A sample of 99 violent and non-violent right-wing extremists to compare their online patterns of desistance within a sub-forum of the largest white supremacy web-forum was analysed. A probabilistic model of desistance was tested to determine the validity of criteria set for users reaching posting desistance. Findings indicated that the criteria predicted “true” desistance, with 5% misidentification. Each consecutive month without posting in the sub-forum resulted in a 7.6% increase in odds of posting desistance. There were no significant differences in effects for violent versus non-violent users, though statistical power was low.

Mobilization is central to the emergence, survival and success of armed groups challenging the state, and has lately expanded to new arenas with the rise of social media. Using a new dataset of rebel group Twitter use, we examined the topics contained in rebel group social media communications to understand how different messaging strategies impact civilian engagement with rebel messages. Rather than benefiting solely from direct calls to action, we found that rebel groups also increased civilian engagement through indirect messages of self-promotion. While direct appeals received more engagement than indirect appeals, their effects were tempered by audience fatigue when relied on too heavily. We additionally found that including images further enhanced the impact of a mobilizing message. These findings expanded our understanding of rebel communications and mobilization, with important implications for combating the use of social media as a recruitment tool for violent extremism.

The Counter-Terrorism Committee unanimously adopted the Delhi Declaration at the closing of its special meeting on countering the use of new and emerging technologies for terrorist purposes, held in India on 28-29 October 2022.

The special meeting focused on three main areas: unmanned aerial systems, terrorist financing and information and communications technologies. The meeting also examined overarching issues relating to the use of technologies for terrorist purposes, to include human rights, gender considerations, and future programming by the international community. The Delhi Declaration provides non-binding guidance to Member States and stakeholders in countering terrorist use of new and emerging technologies.

Scholarship has highlighted the rise of political influencer networks on YouTube, raising concerns about the platform’s propensity to spread and even incentivize politically extreme content. While many studies have focused on YouTube’s algorithmic infrastructure, limited research exists on the actual content in these networks. Building on Lewis’s (2018) classification of an “alternative influencer” network, we apply structural topic modeling across all text-based autocaptions from her study’s sample to identify common topics featured on these channels. This allows us to gauge which topics appear together and to trace politicization over time. Through network analysis, we determine channel similarities and evaluate whether deplatformed channels influenced topic shifts. We find that political topics increasingly dominate the focus of all analyzed channels. The convergence of culture and politics occurs mostly about identity-driven issues. Furthermore, more extreme channels do not form distinct clusters but blend into the larger content-based network. Our findings illustrate how political topics may function as connective ties across an initially more diverse network of YouTube influencer channels.

Approaches for strategically countering or providing alternatives to hate speech and extremism online have evolved substantively in the last ten years. Technological advancement and a generation of young activists who have been socialized as digital natives have facilitated a maelstrom of both hate-based extremist content and attempts to counter this material in different guises and through diverse channels. The rate and pace of change within the tech sector, and social media growth in particular, have meant that although counterspeech is now more prevalent than ever before, it requires greater guidance and more robust public–private partnerships to effectively prevent and counter extremism online. The chapter embraces a cross-platform and international overview of some of the best practices within efforts to prevent and counter violent extremism online and discusses the future of counterspeech with recommendations for expanded innovation and partnership models.
