But there is also a very significant fact: Facebook says that he believes that “most of the people on Facebook may have suffered the scraping of their public profile”. The scraping is the systematic collection of information by third parties through automated systems: this means that the public data entered in Facebook have also been collected from other organisations, and this has happened for at least a billion users.
The tip of the iceberg... I don't know but at this point, actually FB is solid garbage!
