With a size of around 146GB, the data file had data of more than 540 million users, comprising information such as comments, likes, reactions, account names, Facebook IDs and more. This included details such as the Facebook user ID, a list of Facebook friends, likes, photos, groups, checkins, and user preferences like movies, music, books, interests, and other, along with 22,000 passwords.

The database's owner, Cultura Colectiva, has issued a statement, saying the collected data was gathered from fanpages it manages over Facebook, and that the information was openly-shared by users.
