Acute crisis events ranging from natural disasters to terrorist incidents now tend to generate an almost immediate response from social media users. This is especially pronounced on Twitter, due to that platform’s specific affordances as a particularly open and real-time medium. While analyses of such events have increased over recent years, we still understand relatively little about the way in which audiovisual materials relating to such crises are circulated and what they contribute to processes of witnessing. This is important, however, in an increasingly visual age when audiovisual material tends to be more widely viewed and shared than plain-text updates, and thus has a greater potential to influence viewers’ interpretations of an event. To address this gap in our understanding, this article investigates the distribution dynamics of audiovisual content on Twitter in the immediate aftermath of terror attacks in Paris and Brussels. Results point to the importance of broadening conceptualisations of conflict-related visuals and the ongoing relevance of affective content in such material. Furthermore, this article argues that contexts of time and space are crucial to consider, as is the role that individual actors – both human and non-human – play in disseminating such content.

This thesis concerns the possibility of deceiving cyberterrorists using defensive deception methods. As cyberspace today is a battleground for myriad cyber attacks and intrusions, it may only be a matter of time before terrorists choose to advance their deadly cause in cyberspace. We explore some of the questions raised regarding the threat of cyberterrorism by examining different perspectives, motivations, actors, targets, and how they may be confronted. One way is to draw from the lessons of deception and apply them against cyberterrorist attacks. Cyber deception applies in cyberspace just as well as deception in military battles. From the different categories of attackers that could perpetrate cyberterrorism, we examine the ways in which they may be deceived. Many of the methods and tools that cyberterrorists would use are similar to those used by other less malicious hackers, so we can plan specific deceptions to use against them in advance.

Who is likely to be a target of online hate and extremism? To answer this question, we use an online survey (N = 963) of youth and young adults recruited from a demographically balanced sample of Americans. Adapting routine activity theory, we distinguish between actor-initiated social control (i.e., self-help), other-initiated social control (i.e., collective efficacy), and guardianship and show how self-help is positively related to the likelihood of being targeted by hate. Our findings highlight how online exposure to hate materials, target suitability, and enacting social control online all influence being the target of hate. Using social networking sites and encountering hate material online have a particularly strong relationship with being targeted with victim suitability (e.g., discussing private matters online, participating in hate online) and confronting hate also influencing the likelihood of being the target of hate speech.

The 2016 US election and the victory of Donald Trump are closely connected to a perceived rise of the far-right in the United States. We build upon public sphere and alternative media theory to discuss the relevance of alternative media for the US (far-)right and whether the election period and the candidate Trump allowed far-right alternative media to establish themselves in the (far-) right networked public sphere. We investigate whether it has come to a convergence of topics between the right and the extreme far-right. We analyze the topics nine right-wing outlets, ranging from Fox News to the Neo-Nazi Daily Stormer, covered in 2015/2016 during the US presidential election. We show through topic modeling of 21,919 articles how Breitbart established itself as a media outlet between the extreme far-right and mainstream right by both covering more extreme and more classic conservative topics. We show through time series clustering how Breitbart and Fox News converged in their coverage of Islam and immigration. Finally, we show through hyperlink analysis that the connection between the far-right and the mainstream right is mostly one-sided; while the alternative outlets link to more established ones, the established outlets mostly ignore the outlets from the far-right.

This is a formal commentary, responding to Matthew Curran Benigni, Kenneth Joseph, and Kathleen Carley’s contribution, “Online extremism and the communities that sustain it: Detecting the ISIS supporting community on Twitter”. This brief review reflects on the ethics of big data research methodologies, and how novel methods complicate long-standing principles of research ethics. Specifically, the concept of the “data subject” as a corollary, or replacement, of “human subject” is considered.

The rise of QAnon presents researchers with a number of important questions. While emerging literature provides insights into how QAnon exists online, there is a dearth of theoretical engagement with the questions of why it exists, and what conditions brought it into being. This paper seeks to address this gap by contextualizing QAnon as an ontological phenomenon underpinned by anxiety, and inquiring into the identity formation strategies employed by the movement. Applying the basic precepts of discourse theory and discourse analysis to a representative canon of QAnon content, it finds that, like other formations of collective identity, QAnon is premised on interconnected dynamics of ontological fulfillment that cannot be explained away by pointing to ‘the algorithm’ or ‘madness’. Nor can it be tackled effectively by the content takedowns and de-platforming strategies currently employed. The paper concludes with a call to explore more empathetic engagement with conspiracy adherents, arguing that until we (re)discover a more inclusive, agonistic politics, QAnon and other fantastical conspiracy movements will continue to arise and some may metastasize into violent action. New forms of resilience to (online) polarization can be built on this principle.
