Instagram boss Adam Mosseri said he was “deeply moved” by Molly’s story and acknowledged his platform was “not yet where we need to be” on the issues of suicide and self-harm.
Images that encourage the acts are banned, but the boss admitted that Instagram relies on users to report the content before it is purged.
“The bottom line is we do not yet find enough of these images before they’re seen by other people,” Mr Mosseri added.
But he said the Facebook-owned firm would introduce “sensitivity screens” making it harder for users to see images showing cutting.
The issue is not simple though.
He argues a key piece of advice from external experts is that “safe spaces” for young people to discuss their mental health issues online are essential, providing therapeutic benefits.
