Social media is an important source of news and information in the United States. But during the 2016 US presidential election, social media platforms emerged as a breeding ground for influence campaigns, conspiracy, and alternative media. Anecdotally, the nature of political news and information evolved over time, but political communication researchers have yet to develop a comprehensive, grounded, internally consistent typology of the types of sources shared. Rather than chasing a definition of what is popularly known as "fake news," we produce a grounded typology of what users actually shared and apply rigorous coding and content analysis to define the phenomenon. To understand what social media users are sharing, we analyzed large volumes of political conversations that took place on Twitter during the 2016 presidential campaign and the 2018 State of the Union

One of the most contentious and longstanding debates in Internet governance involves the question of oversight of the Domain Name System (DNS). DNS administration is sometimes described as a “clerical” or “merely technical” task, but it also implicates a number of public policy concerns such as trademark disputes, infrastructure stability and security, resource allocation, and freedom of speech. A parallel phenomenon involves governmental and private forces increasingly altering or co-opting the DNS for political and economic purposes distinct from its core function of resolving Internet names into numbers. This article examines both the intrinsic politics of the DNS in its operation and specific examples and techniques of co-opting or altering DNS’ technical infrastructure as a new tool of global power. The article concludes with an analysis of the implications of this infrastructure-mediated governance on network security, architectural stability, and the efficacy of the Internet governance ecosystem.

Previous research has described how highly personalised paid advertising on social media platforms can be used to influence voter preferences and undermine the integrity of elections. However, less work has examined how search engine optimisation (SEO) strategies are used to target audiences with disinformation or political propaganda. This paper looks at 29 junk news domains and their SEO keyword strategies between January 2016 and March 2019. I find that SEO -rather than paid advertising -is the most important strategy for generating discoverability via Google Search. Following public concern over the spread of disinformation online, Google's algorithmic changes had a significant impact on junk news discoverability. The findings of this research have implications for policymaking, as regulators think through legal remedies to combat the spread of disinformation online.

Recently, major social media platforms such as Facebook and Twitter have announced efforts to counter "coordinated inauthentic behaviour." However, scholarly research continues to provide evidence that coordinated human and automated accounts covertly seek to undermine and manipulate public debates on these platforms. Given the difficulties in obtaining data from these platforms to study these influence operations, and the significant challenge of identifying covert malinformation operations, further conceptual and methodological innovations are required. This panel brings together a selection of recent studies that advance the methods available for the forensic, mixed-methods, in-depth, and large-scale analysis of inauthentic information operations: Paper 1 investigates the arson disinformation campaign during the 2019-2020 Australian bushfire season. Paper 2 investigates the distribution and content monetisation strategies of junk news sources across a selection of five major social media platforms during the 2019 European Parliament campaign. Paper 3 explores whether Facebook's microtargeting advertising functionality allows political parties to promote conflicting narratives to different groups of people. Paper 4 studies the experience and engagement with malinformation by users of Facebook and WhatsApp, focussing on the current political environment in Brazil.
