In this article we describe our five-year research project on the notorious radical free speech service and fringe platform Gab. During these years we scraped an entire platform, prepared it into a dataset for analysis, and opened it up to a broader community of students and researchers. Each of these projects provides us not just ...

The article focuses on the role of social media platforms in the radicalization of domestic right-wing terrorists. It discusses a specific case of a mass shooting in Buffalo, New York, where the shooter was radicalized online. It highlights the shooter’s use of social media platforms like 4chan, known for hosting extremist content, and the livestreaming ...

Academic literature widely assumes that extremist-housing online forums, like 4chan, uniformly celebrate acts of right-wing terrorism (e.g. via “sainthood memes”), such as those committed by Anders Breivik and Brenton Tarrant. Aside from a handful of exceptions, this body of research typically fails to acknowledge that ideologically likeminded individuals on 4chan also regularly debate the merits of both ...

Involuntary celibates (incels) are individuals who feel alienated from society because of their perceived inability to attract women. They share a narrative which valorises violence as a means to restructure society according to misogynistic ideals. Since promoting a radical misogynistic ideology through violence is legally prohibited and socially unacceptable, it is necessary for incels to ...

In 1993, a largely forgotten neo-Nazi named Milton Kleim Jr. launched (what was yet to be called a website titled) “Aryan News Network” with the proto-internet platform USENET. Building upon more than a decade of revolutionary new communications technologies—embraced early and often by right-wing extremists—this peer-to-peer tool was intended as a form of ‘guerrilla warfare’ ...

Many cases of radicalism, especially violent radicalism, manifest within the context of inter-ethnic conflict and war. Research in this domain has significantly contributed to our overarching comprehension of the issue. This form of radicalism is inherently linked to the dynamics of group affiliation. However, our focus here is directed towards the individual motivation driving radical ...

In response to the rise of various fringe movements in recent years, from anti-vaxxers to QAnon, there has been increased public and scholarly attention to misinformation and conspiracy theories and the online communities that produce them. However, efforts at understanding the radicalisation process largely focus on those who go on to commit violent crimes. This ...

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 ...

Exposure to radicalizing information has been associated with support for violent extremism. It is, however, unclear whether specific information use behavior, namely, a distinct pattern of incidental exposure (IE) to and active selection (AS) of radicalizing content, indicates stronger violent extremist attitudes and radical action intentions. Drawing on a representative general population sample (N = 1509) ...

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 ...
