An investigation by many independent organizations and media has confirmed the suspicions of many users about how the major social networks like Facebook and MySpace delivers private and relevant information to consumers advertising company or to the CIA without the user consent.
As users generally give their real names, details, pictures, videos, messages and data... it is easy to place them next to a network. This is how Facebook provides the link between the user and a product. The CIA use this information in a way that Julian assange explain in this video, and where the advertising companies receive this valuable information that can be used to find suitable product to these individual profiles.
One of the biggest fears of social network users, especially given the high information published and the high degree of privacy that this information has, is that companies behind these platforms trading are trading with data and your information can come to anybody at any time. These companies will now know your name, taste, political view, religion, future plans, kids...
Earlier and after an internal investigation. The Wall Street Journal did officially confirmed that Facebook, MySpace and other social networks sell private and sensitive information without informing the users.
In the case of Facebook, the investigation showed that the company was going even further than its competitors because the owner not only knew who did click on what but also very detailed information such as which page was been visited and viewed at the time of the click. Unknowingly, with a short path click, the user gives the advertiser a complete profile of who he is.
In January 2008, Tom Hodgkinson published an article in The Guardian denouncing these unhealthy practices. Later it was the turn of the wikileaks founder Julian Assange who denounced these activities. At that time they were greeted with skepticism, but now they have been confirmed.
