A Belgian privacy watchdog says that Facebook is flouting European privacy laws by tracking people without their consent, including those who have not even registered with the social networking site. The Belgian Privacy Protection Commission (CPVP/CBPL) launched the scathing attack after carrying out an investigation into the US tech giant’s practices. Preliminary recommendations were published on Friday. Facebook would not explain in detail how it uses the data it collects from individuals online and there are also problems with plug-ins, some of which can affect people who don’t even have a Facebook account, the commission said. One of the plug-ins under scrutiny was the ‘Like’ button. The social network, the commission noted, has the power to link the browsing habits of internet users to their interactions on the net and other personal data including medical information, and sexual or religious and political preferences. Facebook tramples on European and Belgian privacy laws.
