Video sharing platforms like YouTube are increasingly targeted by aggression and hate attacks. Prior work has shown how these attacks often take place as a result of “raids,” i.e., organized efforts by ad-hoc mobs coordinating from third-party communities. Despite the increasing relevance of this phenomenon, however, online services often lack effective countermeasures to mitigate it. Unlike well-studied problems like spam and phishing, coordinated aggressive behavior both targets and is perpetrated by humans, making defense mechanisms that look for automated activity unsuitable. Therefore, the de-facto solution is to reactively rely on user reports and human moderation. In this paper, we propose an automated solution to identify YouTube videos that are likely to be targeted by coordinated harassers from fringe communities like 4chan. First, we characterize and model YouTube videos along several axes (metadata, audio transcripts, thumbnails) based on a ground truth dataset of videos that were targeted by raids. Then, we use an ensemble of classifiers to determine the likelihood that a video will be raided with very good results (AUC up to 94%). Overall, our work provides an important first step towards deploying proactive systems to detect and mitigate coordinated hate attacks on platforms like YouTube.

The internet offers tremendous opportunities for violent extremists across the ideological spectrum and at a global level. In addition to propaganda, digital technologies have transformed the dynamics of radical mobilisation, recruitment and participation. Even though the jihadist threat has seemingly declined in the West, the danger exists of the internet being an environment where radical messages can survive and even prosper. Against this background, this ISPI report investigates the current landscape of jihadist online communication, including original empirical analysis. Specific attention is also placed on potential measures and initiatives to address the threat of online violent extremism. The volume aims to present important points for reflection on the phenomenon in the West (including Italy) and beyond.

One of the paradoxical effects of the 7 July bombings in London was to expose the ambivalence in the British government’s attempt to wage war on terror by forcefully prosecuting war against those who resort to jihad abroad, actively participating in coalitions of the willing whether in Afghanistan or Iraq, while affording some of Islamism’s key ideologists and strategists a high degree of latitude in the United Kingdom itself. This indicates a number of contradictions in official policy that simultaneously recognizes the globalized threat from violent Islamic militancy while, under the rubric of multiculturalism, tolerating those very strains of Islamist radicalism, some of which draw upon the interdependent and transnational character of conflict, to render the UK vulnerable to those very same violent forces. Consequently, the British authorities displayed a studied indifference towards this developing transnational phenomenon both during the 1990s and in some respects even after the London bombings. To explore the curious character of the government’s response to the Islamist threat requires the examination of the emergence of this radical ideological understanding and what it entails as a reaction to modernization and secularism in both thought and practice. The analysis explores how government policies often facilitated the non-negotiable identity politics of those promoting a pure, authentic and regenerated Islamic order both in the UK and abroad. This reflected a profound misunderstanding of the growing source and appeal of radical Islam that can be interpreted as a consequence of the slow-motion collision between modernity in its recent globalized form and an Islamic social character, which renders standard western modernization theory, and indeed, the notion of a ‘social science’ itself, deeply questionable.

Through a descriptive and qualitative content analysis of Al-Qaeda videos from 2001 to 2010, this thesis describes how the organization‘s video production has undergone a surge in production quality by using modern technology and skilled recruits. This thesis also provides background on the Islamic culture and the history of Al-Qaeda in order to put into perspective the goals of the organization‘s framed messages that are incorporated into their videos. The study also draws on the parallels of propaganda used throughout history to highlight how regimes from all over the world understand the importance of communication during a time of war.
