Recognizing the correlation between the growing spread of violent extremist and terrorist content on the internet and online platforms and the significant increase in attacks inspired by these posts prompted governments, security agencies, and private companies to launch various countermeasures to reduce the spread and impact of such material. Struggling to adjust to these countermeasures and maintain their online presence, terrorists and violent extremists have migrated from mainstream online platforms to alternative online channels like 4chan, 8chan, Telegram, TikTok, and most recently to the new platform TamTam. This paper describes the migration to and within social media generally, with a specific focus on the newly discovered migration to the platform TamTam and presents the results of our extensive content analysis of hundreds of posts and shares containing terrorist and violent extremist content on this platform. These findings are discussed in terms of ethical and practical implications.

This report reviews propaganda and social media activities of jihadists and right-wing extremist (RWE) groups and assesses the impact of the fall of Kabul on their narratives.

This article is an empirical study of the visual mobilization strategies implemented by terrorist organizations seeking recruits or fighters. Drawing on the interdisciplinary theoretical approach of social movement studies and international relations and security studies, the author focuses on the propaganda narratives used by the Daesh organization from its inception to the COVID-19 pandemic. Between 2011 and 2022, the Daesh organization produced several publications and recordings containing migratory rhetoric, combined with provocative gender images and political or climate themes. Approaching terrorist propaganda through the lens of actors constructing visual forms of political mobilization, the article shows how the analyzed organizations are supported by professional graphic designers commercializing extremist ideologies by creating ambivalent images and text messages. In doing so, they construct a multidimensional environment that fosters reciprocal and cumulative radicalization.

The purpose of this study is to synthesize the literature relating to radicalization on social media, a space with enhanced concerns about nurturing propaganda and conspiracies for violent extremism. Through the systematic review of 82 peer-reviewed studies related to radicalization through social media published in scholarly journals, this paper evidence the growth of robust studies on the usage of social media for radicalization. Nonetheless, the current work hardly discusses the radicalization issues through social media and reveals an increasing trend of publication from 2017 with a major contribution from the USA, Germany, and England. The thematic analysis indicated determinants of radicalization and the mitigation measures for the deradicalization of content on social media. However, the knowledge gap persists to understand the effects of radicalization in the different regional settings and further framing of content specific to target populations. Individuals must have the critical social media literacy to counteract the rising radicalization through social media. Individual users’ political interests are key factors in their radicalization such as citizens losing faith in the government and political parties. Active rather than passive searchers of violent radical material are more likely to engage in political violence. The results indicate that further research using experimental design, grounded theory, and pilot interventions may be relevant to suggest a solution to mitigate radicalization on social media.
