VOX-Pol Guest Lecture Series, Spring 2024: Data Collection in Online Terrorism and Extremism Research

There has been a growing interest among researchers, practitioners, and policymakers to analyze the online activities of extremists and terrorists. As studies in this research area have increased, various data collection techniques have emerged to address key research questions, ranging from manual extraction to computational tools to collect online information. This lecture examines the strengths and limitations of commonly used data collection methods in online terrorism and extremism research. We draw from our research experiences and highlight ethical dilemmas with collection methods in practice. We then set forth suggestions for progressing research in this space. For more information on data collection in online terrorism and extremism research, see our recent article in Studies in Conflict & Terrorism as part of a special issue on the strengths and struggles of different methods of research on radicalization, extremism, and terrorism: https://www.tandfonline.com/doi/full/10.1080/1057610X.2024.2361957?src=exp-la

Despite the ongoing need for practitioners to identify violent extremists online before their engagement in violence offline, little is empirically known about their digital footprints generally or differences in their posting behaviors compared to their non-violent counterparts particularly – especially on high-frequency posting days. Content analysis was used to examine postings from a unique sample of violent and non-violent right-wing extremists as well as from a sample of postings within a sub-forum of the largest white supremacy forum during peak and non-peak posting days for comparison purposes. Several noteworthy posting behaviors were identified that may assist in identifying credible threats online.

Researchers have previously explored how right-wing extremists build a collective identity online by targeting their perceived “threat,” but little is known about how this “us” versus “them” dynamic evolves over time. This study uses a sentiment analysis-based algorithm that adapts criminal career measures, as well as semi-parametric group-based modeling, to evaluate how users’ anti-Semitic, anti-Black, and anti-LGBTQ posting behaviors develop on a sub-forum of the most conspicuous white supremacy forum. The results highlight the extent to which authors target their key adversaries over time, as well as the applicability of a criminal career approach in measuring radical posting trajectories online.

Although there is an ongoing need for law enforcement and intelligence agencies to identify and assess the online activities of violent extremists prior to their engagement in violence offline, little is empirically known about their online posting patterns generally or differences in their online patterns compared to non-violent extremists who share similar ideological beliefs particularly. Even less is empirically known about how their online patterns compare to those who post in extremist spaces in general. This study addresses this gap through a content analysis of postings from a unique sample of violent and non-violent right-wing extremists as well as from a sample of postings within a sub-forum of the largest white supremacy web-forum, Stormfront. Here the existence of extremist ideologies, personal grievances, and violent extremist mobilization efforts were quantified within each of the three sample groups. Several notable differences in posting patterns were observed across samples, many of which may inform future risk factor frameworks used by law enforcement and intelligence agencies to identify credible threats online. This study concludes with a discussion of the implications of the analysis, its limitations, and avenues for future research.
