Countering terrorism or criminalizing curiosity? The troubled history of UK responses to right-wing and other extremism
View Abstract
The growth of right-wing extremism, especially where it segues into hate crime and terrorism, poses new challenges for governments, not least because its perpetrators are typically lone actors, often radicalized online. The United Kingdom has struggled to define, tackle or legitimate against extremism, though it already has an extensive array of terrorism-related offences that target expression, encouragement, publication and possession of terrorist material. In 2019, the United Kingdom went further to make viewing terrorist-related material online on a single occasion a crime carrying a 15-year maximum sentence. This article considers whether UK responses to extremism, particularly those that target non-violent extremism, are necessary, proportionate, effective and compliant with fundamental rights. It explores whether criminalizing the curiosity of those who explore radical political ideas constitutes legitimate criminalization or overextends state power and risks chilling effects on freedom of speech, association, academic freedom, journalistic enquiry and informed public debate—all of which are the lifeblood of a liberal democracy.

On the Origins of Memes by Means of Fringe Web Communities
View Abstract
Internet memes are increasingly used to sway and manipulate public opinion. This prompts the need to study their propagation, evolution, and influence across the Web. In this paper, we detect and measure the propagation of memes across multiple Web communities, using a processing pipeline based on perceptual hashing and clustering techniques, and a dataset of 160M images from 2.6B posts gathered from Twitter, Reddit, 4chan’s Politically Incorrect board (/pol/), and Gab, over the course of 13 months. We group the images posted on fringe Web communities (/pol/, Gab, and The_Donald subreddit) into clusters, annotate them using meme metadata obtained from Know Your Meme, and also map images from mainstream communities (Twitter and Reddit) to the clusters. Our analysis provides an assessment of the popularity and diversity of memes in the context of each community, showing, e.g., that racist memes are extremely common in fringe Web communities. We also find a substantial number of politics-related memes on both mainstream and fringe Web communities, supporting media reports that memes might be used to enhance or harm politicians. Finally, we use Hawkes processes to model the interplay between Web communities and quantify their reciprocal influence, finding that /pol/ substantially influences the meme ecosystem with the number of memes it produces, while td has a higher success rate in pushing them to other communities.

What is Gab? A Bastion of Free Speech or an Alt-Right Echo Chamber?
View Abstract
Over the past few years, a number of new “fringe” communities, like 4chan or certain subreddits, have gained traction on the Web at a rapid pace. However, more often than not, little is known about how they evolve or what kind of activities they attract, despite recent research has shown that they influence how false information reaches mainstream communities. This motivates the need to monitor these communities and analyze their impact on the Web’s information ecosystem. In August 2016, a new social network called Gab was created as an alternative to Twitter. It positions itself as putting “people and free speech first'”, welcoming users banned or suspended from other social networks. In this paper, we provide, to the best of our knowledge, the first characterization of Gab. We collect and analyze 22M posts produced by 336K users between August 2016 and January 2018, finding that Gab is predominantly used for the dissemination and discussion of news and world events, and that it attracts alt-right users, conspiracy theorists, and other trolls. We also measure the prevalence of hate speech on the platform, finding it to be much higher than Twitter, but lower than 4chan’s Politically Incorrect board.

Vom Analogen ins Digitale. Eine kurze Geschichte der dschihadistischen Propaganda und ihrer Verbreitung
View Abstract
Der Beitrag bietet eine kurze Einführung in die Geschichte dschihadistischer Propaganda von den 1980er Jahren bis in die Gegenwart. Nicht nur die medientechnologische und -kulturelle Entwicklung, sondern auch geopolitische Konfliktgeschichte mit wichtigen Stationen wie der sowjetischen Intervention in Afghanistan und dem ersten Tschetschenienkrieg sind hier ausschlaggebend. Was die Entwicklung auf dem Feld der Online-Propaganda betrifft, stützt sich der Verfasser auch auf eigenen Erfahrungen im Rahmen der Beobachtung und Analyse dschihadistischer Internet-Auftritte und -Kommunikatverbreitung.

Jillian C. York on Freedom of Expression and Safety Online
View Abstract
Is it possible to guarantee users online safety while also guaranteeing the right to freedom of expression? If there are limits to be placed on speech, who decides? In her keynote lecture of the VOX-Pol summer school on topics in violent online political extremism hosted by the Center for Media, Data and Society at the CEU School of Public Policy, Jillian C. York examines these questions, and looks at the current state of freedom of expression on the Internet, as well as the grave threats it faces. Jillian C. York is a writer and activist focused on the intersection of technology and policy. Based in Berlin, she serves as the Director for International Freedom of Expression at the Electronic Frontier Foundation, where she works on issues of free expression, privacy, and digital security. Jillian is also a fellow at the Center for Internet & Human Rights at the European University Viadrina, and a member of the Deep Lab collective.

EEG distinguishes heroic narratives in ISIS online video propaganda
View Abstract
The Islamic State (ISIS) was uniquely effective among extremist groups in the Middle East at recruiting Westerners. A major way ISIS accomplished this was by adopting Hollywood-style narrative structures for their propaganda videos. In particular, ISIS utilized a heroic martyr narrative, which focuses on an individual’s personal glory and empowerment, in addition to traditional social martyr narratives, which emphasize duty to kindred and religion. The current work presented adult participants (n = 238) video clips from ISIS propaganda which utilized either heroic or social martyr narratives and collected behavioral measures of appeal, narrative transportation, and psychological dispositions (egoism and empathy) associated with attraction to terrorism. Narrative transportation and the interaction between egoism and empathy predicted video recruitment appeal. A subset of adults (n = 80) underwent electroencephalographic (EEG) measurements while watching a subset of the video-clips. Complementary univariate and multivariate techniques characterized spectral power density differences when perceiving the different types of narratives. Heroic videos show increased beta power over frontal sites, and globally increased alpha. In contrast, social narratives showed greater frontal theta, an index of negative feedback and emotion regulation. The results provide strong evidence that ISIS heroic narratives are specifically processed, and appeal to psychological predispositions distinctly from other recruitment narratives.
