Matt Hancock, the UK health secretary, has called on social media giants to ‘purge’ material promoting self-harm and suicide, in the wake of links to teenager Molly Russell's suicide. They could be banned if they fail to comply. The 14-year-old took her life after viewing disturbing content about suicide on Instagram. Her father believed Instagram ‘helped kill my daughter’. Instagram owners, Facebook, said they were ‘deeply sorry’. The charity Papyrus, working to prevent youth suicide, had a spike in calls to their helpline after the BBC reported the link between suicide and social media. Meanwhile, Facebook removed 364 ‘fake’ pages (with 790,000 followers) for engaging in coordinated inauthentic behaviour as part of a network that originated in Russia. Facebook said the page administrators and account owners represented themselves as independent news pages or general interest pages, but all were linked to employees of Russian-owned Sputnik and the facts were false.
