The use of social media to disseminate extreme political content on the web, especially right-wing populist propaganda, is no longer a rarity in today’s life. Recommendation systems of social platforms, which provide personalized filtering of content, can contribute to users forming homogeneous cocoons around themselves. This study investigates YouTube’s recommendations system based on 1,663 German political videos in order to analyze the homogeneity of the related content. After examining two datasets (right-wing populist and politically neutral videos), each consisting of ten initial videos and their first and second level recommendations, we show that there is a high degree of homogeneity of right-wing populist and neutral political content in the recommendation network. These findings offer preliminary evidence on the role of YouTube recommendations in fueling the creation of ideologically like-minded information spaces.

The polarizing tendency of politically leaned social media is usually claimed to be spontaneous, or a by-product of underlying platform algorithms. This contribution revisits both claims by articulating the digital world of social media and rules derived from capitalist accumulation in the post-Fordist age, from a transdisciplinary perspective articulating the human and exact sciences. Behind claims of individual freedom, there is a rigid pyramidal hierarchy of power heavily using military techniques developed in the late years of the cold war, namely Russia Reflexive Control and the Boyd’s decision cycle in the USA. This hierarchy is not the old-style “command-and-control” from Fordist times, but an “emergent” one, whereby individual agents respond to informational stimuli, coordinated to move as a swarm. Such a post-Fordist organizational structure resembles guerrilla warfare. In this new world, it is the far right who plays the revolutionaries by deploying avant-garde guerrilla methods, while the so-called left paradoxically appears as conservatives defending the existing structure of exploitation. Although the tactical goal is unclear, the strategic objective of far-right guerrillas is to hold on to power and benefit particular groups to accumulate more capital. We draw examples from the Brazilian far right to support our claims.

This article offers a descriptive analysis of the private interactions which took place on the jihadist Internet forum known as Ansar Al Mujahideen between 2008 and 2010. The analysis of the non-visible part of the forum contributes to a more robust underpinning of some current assumptions regarding the jihadist Internet infrastructure and its hierarchical dependence on, and subordination to, formal terrorist organisations and charismatic leaders. In addition, it offers a new perspective on other aspects such as the many conflicts and rivalries between the different forums, the operational constraints caused by the lack of human and material resources, and the considerable vulnerability of the forums to cyber-sabotage and infiltration attempts.

The number of lone-actor attacks committed by far-right extremists have surged in recent years, most notably in the West where mass-casualty attacks have occurred, including the United States, New Zealand, the United Kingdom, and Germany. The fatal attack in February 2020 in Hanau,
Germany, revealed the perpetrator’s influences to be a combination of traditional far-right, race-based, and anti-immigration narratives, alongside several more obscure conspiracy theories. This case demonstrates the need for further research into the intersection of these ideas and the online ecosystems in which they thrive, where notions such as the “Great Replacement” theory, aspects of which were echoed in the Hanau attacker’s own manifesto, are heavily propagated. It is this overarching idea that connects seemingly disparate attacks in a global network of ideologically analogous acts of terror.

The role of online communities of the extreme-right in the radicalization of individuals involved in political violence has received increased public attention due to recent tragic events around the world. In this policy brief, we provide a systematic account of the psychological processes underpinning the formation and transformation of these communities. Our analysis is built on the premise that these communities can be understood as ideologically driven psychological groups, and as such their collective beliefs, values, and norms are key to understanding their actions. Drawing on findings from research into an Australian extreme-right online community, we show how these collective beliefs, values, and norms can change in the aftermath of particular socio-political events in the offline domain. We conclude by proposing strategies that can be used to direct policy and recommendations for research in the area.

This study focuses on the formation of far-right online communities on YouTube and whether the rise of three new actors (Pegida, Identitarian movement, AfD) can also be observed with user behavior on YouTube. We map the network of far-right, conspiracy and alternative media channels in the German-language YouTube sphere, how this network evolves over time and identify the topics that users discuss. Our analysis shows that the overall common denominator within the German far-right YouTube sphere is the refugee crisis and the problems associated with it. Furthermore, we show that the community is getting denser and more centralized over time.
