Das Wall Street Journal berichtet über die Weitergabe persönlicher Nutzerprofile an Werbekunden der großen sozialen Netzwerke (Facebook, MySpace, etc.).
Facebook, MySpace and several other social-networking sites have been sending data to advertising companies that could be used to find consumers‘ names and other personal details, despite promises they don’t share such information without consent. […] Advertising companies are receiving information that could be used to look up individual profiles, which, depending on the site and the information a user has made public, include such things as a person’s real name, age, hometown and occupation.
Weitaus ausführlicher berichtet hierüber Ben Edelman, derjenige, der das Datenleck entdeckt hat.
