Blank spaces indicate no evidence was found. Strategies, Tools, and Techniques Whilst computational propaganda has been in use in Brazil since 2010, it was particularly evident in the 2018 elections, and “fake news” became a major concern. Authorities were handling sanctions quickly, and the Superior Electoral Court (Tribunal Superior Eleitoral, TSE) subpoenaed Facebook to remove over 196 pages that contained false information, including the page of Movimento Brasil Livre, a major force in the impeachment of Rousseff and Bolsonaro’s rise (Maleronka & Declercq, 2018). Brazil has shown quite an innovative spirit towards political propaganda and the 2018 election was marked by a few incidents illustrating this characteristic. First, the concept of politicians as social media celebrities and influencers is not a novel phenomenon in Brazil. In fact, the current President Jair Bolsonaro started doing live-broadcasts and putting videos on YouTube as early as 2016. Interestingly, this approach took on a different direction when certain politicians became carriers of disinformation themselves. Congresswoman Joice Hasselmann spread false information accusing the Rousseff’s Workers’ Party of having ties with the Hezbollah (Joao Filho & Felizardo, 2018). She also alleged that one of the mainstream media companies had a contract worth up to 600 million reais (approximately £130 million) to support the Workers’ Party. In the weeks leading up to the first round of elections, which took place on 3 October 2018, Brazilians complained about the large volume of disinformation circulating on social media. However, research by the Oxford Internet Institute has shown that traffic on Twitter was particularly low (Machado et al., n.d.). Multiple reports released in the period between the first and second rounds of voting, along with findings from investigative journalists, showed that the bulk of Brazilian disinformation was being disseminated through WhatsApp. Over 120 million Brazilians use the platform regularly, making it an effective way of reaching the entire population (Paulo Higa, 2018). As research has shown, the total volume of disinformation spread over WhatsApp was at least eleven times greater than the total dissemination of junk news on Twitter, and clustered networks of WhatsApp groups were used to disseminate disinformation to thousands of users (Machado et al., 2019). 60
