The aim of this research is to study the misinformation processes that circulated during the presidential elections held in Argentina on October 27, 2019. These elections were presented as an interesting case study in which the candidates Mauricio Macri and Alberto Fernandez were fighting for the government in a economic crisis and with a divided society. The disinformation strategies were a fact, although in May press associations, digital platforms and political parties signed an agreement to combat false news on social media. In the research now presented, we analyze the role of Reverso -an initiative promoted and coordinated by Chequeado, AFP Factual, First Draft and Pop-Up Newsroom-. Within Reverso, more than 120 media and technology companies joined together to tackle misinformation during the electoral process. This research is based on obtaining and analysing the tweets published by Reverso on its Twitter account between 16 May and 29 October 2019. As results of the research, a typology of hoaxes and debunks that circulated as well as the identification of the preferential distribution channels of these hoaxes stand out.
