เป้สะพายหลัง ยี่ห้ออะไรดี src="http://ichef-1.bbci.co.uk/news/320/cpsprodpb/138CA/production/_95147008_037217223-1.jpg" width='250px' alt='Heiko Maas' align='left' /> Heiko Maas said the voluntary efforts of social networks to tackle the problem had not gone far enough. The proposal requires sites to run 24-hour helplines and to delete flagged content within seven days. 'Utterly impossible' Social media firms such as Twitter and Facebook were getting better at handling illegal content, said Mr Maas, but both had a long way to go. Mr Maas quoted research which suggested Twitter deletes only 1% of the hate speech it is told about by users, and Facebook, 39%. "This isn't sufficient yet," said Mr Maas. Racism and hate speech are believed to have become more prevalent on German social media following the arrival of large number of refugees in Germany. Any content that was "clearly criminal" would have to be removed within 24 hours under conditions outlined in the draft law. If, after an investigation, content is found to be criminal then that must be removed in seven days. The people who posted the illegal content must also be told about its deletion.
