Germany aims to pass new laws on social media after revelations that Facebook data was used to manipulate voters. "In future we will clearly have to monitor companies like Facebook more strictly and punish data protection violations severely and quickly," German Justice Minister Katarina Barley told press in Berlin on Monday. "We'll need much tighter supervision of companies like Facebook." Barley added that firms like Facebook should tell users in "clear, precise and simple language" how their data will be used, and described what happened at the US firm as "intolerable."
