“Britain has threatened Mr Zuckerberg, 34, with legal action if Facebook - with two billion users - fails to take down content glorifying Islamic State terrorists, as politicians grow increasingly impatient with the lawless nature of the internet. He has refused to appear before a special Grand Committee convened by MP Damian Collins, chairman of the Commons Digital, Culture, Media and Sport Committee in London next week. Mr Collins wanted assurances about breaches of data protection and to ask why the Californian tech giant, worth £105 billion, did not do more to act against 'disinformation' posts - especially from Russia. Mr Collins also wanted to give Mr Zuckerberg the dossier of depravity the Daily Express passed to him last week. Facebook said it was taking unprecedented steps to remove hate posts and had taken down a billion fake accounts. But David Ibsen, executive director of the international Counter Extremism Project (CEP), said: "Facebook's smokescreen is window dressing.'Just the same as the claims Mr Zuckerberg made before the US Congress that the company's algorithms remove 99 per cent of Isis and al-Qaeda online content.' The Daily Express and the CEP compiled a dossier of hate filled material found on Facebook - which is only meant to be used by those aged 13 and over.”
