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.

Drawing on a survey of 13,302 online Australians, this study examines the characteristics and behaviours of respondents who viewed child sexual abuse material (CSAM) and fringe or radical content online, or both. In the past 12 months, 40.6 percent of respondents had viewed fringe or radical content and 4.5 percent had viewed CSAM. Among respondents who viewed CSAM, 64.7 percent had also viewed fringe or radical content, while 7.1 percent of those who viewed radical content had also viewed CSAM. Respondents who viewed only CSAM or only fringe or radical content were similar to one another. Respondents who viewed both were more likely to be younger and male and had higher rates of criminal justice system contact and diagnosed mental illness. Their online activity, including the platforms used, also differed.

This chapter addresses the impact and discomfort of researching extremist digital subcultures. It provides reflections about the visual and personal dimension from two researchers investigating online extremist far-right and incel content, using memes as a case study. Through visually stimulating images, humor, and narratives, memes can normalize and desensitize extremism and violence, not only for the consumers but also for the researchers. We compare our research experiences to help prepare others who plan to study extremist content online by identifying themes of dehumanization and provocation, internalization and enabling harmful humor, and hyperawareness in everyday life. We give specific suggestions for handling these challenges and conclude by discussing the importance of adopting a reflexive approach for orienting our positionality in the research process.

Social media has become a critical tool for terrorist groups like ISIS and Al-Qaeda, leveraging these platforms to disseminate ideology, recruit members, and mobilize support. This study aims to identify the patterns of terrorist propaganda on social media and develop effective digital communication strategies to counteract these activities. The research employs a qualitative approach through literature review and content analysis, grounded in digital communication, strategy, and propaganda theories. The findings reveal that terrorist groups utilize emotional narratives to disseminate ideology, personalized approaches for recruitment, and social media to organize collective actions. Successful digital communication strategies include AI-based early detection, culturally relevant counter-narratives, digital literacy to raise public awareness, cross-sector collaboration, and robust law enforcement. The study’s holistic approach is essential to counter terrorist propaganda, emphasizing close collaboration among governments, technology companies, and society. Further research is recommended to explore emerging technologies and innovative strategies to address the evolving threat.

This project aims to understand, through a gender and intersectional lens, how socialisation processes coupled with exposure to harassment, hate-based discrimination and extreme content can potentially lower resilience to radicalisation in gaming.

Researchers are increasingly conducting research using primary source data involving observation of, and exposure to, violent extremist individuals, their acts, their online content, and the ideologies that they act in support of. Of concern is that this increased use of primary source material has not occurred alongside a serious investigation of the traumatic outcomes that may result from constant exposure to such materials within the process of conducting academic research. As such, the goal of this review is to conduct a rapid evidence assessment to identify (a) What theories currently exist that conceptualize trauma stemming from vicarious observation of extremist atrocities? (b) In what similar domains (if any) have researchers conceptualized the trauma that stems from vicarious observation of extremist atrocities? (c) What is the current evidence base for these theories? And (d) What are the immediate research needs to extend this research and support the research workforce? Articles were identified using search strings related to types of trauma, and relevant domains of work (e.g., criminal justice, healthcare, national security, content moderation). In total 34 articles were screened and assessed in full. The work domains of these articles ranged from drone warfare to digital forensics and interrogation interpreters. Overall, exposure to traumatic images, videos, and events is associated with burnout, secondary traumatic stress, turnover intentions, and a host of wider negative psychosocial outcomes. Furthermore, this process is impacted by several factors including the nature of the content, the wider organizational culture, and individual differences.
