2.Debunking: information aiming at correcting false conspiracy theories and untruthful rumors circulating online (for the US dataset).

To produce our datasets, we built a large atlas of Facebook public pages with the assistance of several groups (Skepti Forum, Skeptical spectacles, Butac, Protesi di Complotto), which helped in labelling and sorting both conspiracy and scientific sources. To validate the list, all pages have then been manually checked by looking at their self-description and the type of promoted content. The exact breakdowns of the Italian and US Facebook datasets are reported in Tables 1 and 2, respectively. The entire data collection process is performed exclusively by means of the Facebook Graph API [24], which is publicly available and can be used through one’s personal Facebook user account. We used only public available data (users with privacy restrictions are not included in our dataset). Data was downloaded from public Facebook pages that are public entities. Users’ content contributing to such entities is also public unless users’ privacy settings specify otherwise and in that case it is not available to us. When allowed by users’ privacy specifications, we accessed public personal information. However, in our study we used fully anonymized and aggregated data. We abided by the terms, conditions, and privacy policies of Facebook. Table 1Breakdown of the Italian Facebook dataset
