Promoted by the Magna Grecia Foundation, a course of study that kicked off with the conference "Mafias in the time of social media" in May 2022 and which gave rise to the Report bearing the same name. The research investigated for the first time the presence of content related to mafias, but also produced by individuals connected to them, on social networks, analysing practices, symbols, meanings, narratives and networks. The research team, coordinated by Prof. Marcello Ravveduto of the University of Salerno, processed and analysed thousands of data for a year, using innovative methodological approaches. The Report is the first in a series that, from year to year, will monitor the processes related to the scope of analysis through specific annual assessments. The Report was presented on 2 March 2023 at the conference room of the Foreign Press Association in Rome.
