The Regional Hubs are a network of research groups spread across several regions of Brazil dedicated to monitoring the dynamics of disinformation campaigns and the construction of harmful narratives about elections and climate issues on digital platforms. The first edition focuses on the 2024 municipal elections. The goal is to identify the prevalence and circulation of content that is harmful to electoral integrity on TikTok, in addition to observing how candidates use this short video platform. With this, we seek to expand the capacity to analyze information flows based on short videos, in a decentralized manner, and in tune with the technological and political realities of each region.
