Today, data extracting and selling are no longer activities kept in secret from the world's most rated companies, like Facebook. Although, not all data are as trustful, pure and clear like other.
It's not a lie that people that are getting concerned about their data security and privacy are more "disguised" when they are making informations about themselves, I mean, photos, names, wishes, Chrome searches, likes, preferences, ages, etc. How can a data extraction be productive if not all of them are really trustful? Are companies making searches based on random and manipulated informations about society's desires?
