NetLab UFRJ monitored the main social media platforms in real time during the election campaign blackout period, from 48 hours before to 24 hours after the second-round election.

During the first month of the election campaign, between August 16 and September 16, NetLab UFRJ collected and analyzed 6,757 ads run on Meta platforms to map content discussing the electoral process, the institutions responsible for conducting it, and their representatives.
