Incels, a portmanteau of the term involuntary celibates, operate in online communities to discuss difficulties in attaining sexual relationships. Past reports have found that multiple elements of the incel culture are misogynistic and favorable towards violence. Further, several violent incidents have been linked to this community, which suggests that incel communities may resemble other ideologically ...

Many researchers, practitioners, and policymakers are concerned about online communities that are known to facilitate violent right-wing extremism, but little is empirically known about these digital spaces in general and the developmental posting behaviors that make up these spaces in particular. In this study, group-based trajectory modeling—derived from a criminal career paradigm—was used to identify ...

Donald Trump’s 2016 electoral victory was a shock for feminist scholars, yet it was no surprise to his legion of supporters in alt-right digital spaces. In this essay, we analyze one of the online forums that helped propel Trump to electoral victory. Drawing on social movement concepts and an analysis of 1,762 posts, we show ...

The increased threat of right-wing extremist violence necessitates a better understanding of online extremism. Radical message boards, small-scale social media platforms, and other internet fringes have been reported to fuel hatred. The current paper examines data from the right-wing forum Stormfront between 2001 and 2015. We specifically aim to understand the development of user activity ...

In this paper we present a novel interactive multimodal learning system, which facilitates search and exploration in large networks of social multimedia users. It allows the analyst to identify and select users of interest, and to find similar users in an interactive learning setting. Our approach is based on novel multimodal representations of users, words ...

Online discussion forums provide open workspace allowing users to share information, exchange ideas, address problems, and form groups. These forums feature multimodal posts and analyzing them requires a framework that can integrate heterogeneous information extracted from the posts, i.e. text, visual content and the information about user interactions with the online platform and each other. ...

Drawing from Life Course Theory (LCT) and General Strain Theory (GST), the current study sought to address the development of negative affect in the online context, specifically whether the turning point of entrance into adulthood was associated with a change in the sentiment expressed online. A mixed-methods approach was employed, whereby 96 individuals were sampled ...

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, ...

Gatekeeping is defined as the work of third parties “who are able to disrupt misconduct by withholding their cooperation from wrongdoers.”1 Internet intermediaries need to be far more proactive as gatekeepers than they are now. Socially responsible measures can prevent the translation of violent thoughts into violent actions. Designated monitoring mechanisms can potentially prevent such ...

The threat posed by terrorism today is changing rapidly—as have methods of study of this phenomenon, including analysis of radicalisation and the ‘terrorist cycle’. This chapter takes a qualitative approach to one aspect of contemporary terrorism, self-directed (‘lone wolf’) terrorism by right-wing extremists. Predominately plaguing the USA at first, solo actor terrorism by fascist extremists ...
