“…In the last half-decade, mobile instant messaging services (MIMS) have become a matter of concern for governments, civil society, and academic researchers, due to their opacity and the difficulty of monitoring the circulation of content harmful to democracy, such as mis/disinformation and hate speech, which particularly flood the discussion groups they host (Rossini; Stromer-Galley; De-Oliveira, 2020; Banaji; Bhat, 2019). There is a recent but vast literature that has sought to discuss these platforms, with an emphasis on specific services, such as WhatsApp (Bursztyn;Birnbaum, 2019), Telegram (Willaert et al, 2022;Santos;Saldaña;Tsyganova, 2021), and WeChat (Wu;Wall, 2019), among others. And although, among these three examples, Russian and Chinese private messaging services equally pose challenges for their respective contexts, it is WhatsApp, due to its enormous popularity, especially in non-Western countries such as Brazil and India, that has boosted public debate around issues such as the spread of fake news (Resende et al, 2019;Sacramento;Paiva, 2020), and increased distrust in democratic institutions (Piaia;Alves, 2020), political radicalization (Evangelista;Bruno, 2019), and dangerous speech (Saha et al, 2021;Matamoros-Fernández, 2020).…”
