The European Commission has warned EU citizens that they should close their Facebook accounts if they want to keep information private from US security services, finding that current Safe Harbour legislation does not protect citizen's data.

The comments were made by EC attorney Bernhard Schima in a case brought by privacy campaigner Maximilian Schrems, looking at whether the data of EU citizens should be considered safe if sent to the US in a post-Snowden revelation landscape.

"You might consider closing your Facebook account, if you have one," Schima told attorney general Yves Bot in a hearing of the case at the European court of justice in Luxembourg.
