Pablo Ortellado, at the University of São Paulo, studies the way social media are used for political purposes. ‘We analyse all the messages that we believe come from Bolsonaro and his supporters. It makes you want to cry,’ Ortellado told me. ‘At the beginning of the Covid-19 epidemic for example, people everywhere were receiving messages saying that Covid doesn’t kill, that it was made-up by the Chinese, that the hospitals are not full. There is nothing we can do about this spread of misinformation because it has already gone viral.’ Bolsonaro relies on Whatsapp more than Twitter or Facebook. ‘Because it is a private messenger app as opposed to a public platform,’ Ortellado says, ‘we believe it allows the president to disseminate malicious misinformation to millions of people without being caught.’
