An external agency paid by the Qatari-owned Paris club created an “army” of fake Twitter accounts which then carried out aggressive and foul-mouthed online smear campaigns, in particular against the media and some of the Paris football club's own leading figures. Mediapart and the sports newspaper L’Équipe were among the main targets. This “digital army” even had a go at PSG's French star Kylian Mbappé. Clément Fayol and Yann Philippin report.
