Head of Child Safety Online at the NSPCC, Rani Govender, said: "When a young person is sexually extorted, it can be devastating for them and their families. And these figures make it clear that more children will continue to fall victim to this horrific crime if platforms fail to act with urgency.
"With the Government's promise last month to introduce legislation making nudity-blocking technology compulsory on children's devices, tech companies must now to use the resources at their fingertips and make the changes.
"Without swift action from tech companies and the Government, this abuse will only get worse. There is no excuse for inaction."
Report Remove is a free, confidential helpline run by the Internet Watch Foundation (IWF) and the NSPCC’s Childline.
It allows under 18s in the UK to self-report suspected nude or sexual imagery of themselves which has been shared, or risks being shared, online. The imagery can then be blocked and removed.
Crucially, this can be done pre-pre-emptively, before criminals have had a chance to put imagery on the open web. This means Report Remove is a crucial tool for neutralising criminal’s threats and giving young people facing sextortion control over their images.
Under-18s in the UK can self-report suspected nude or sexual imagery of themselves via Report Remove.
If the imagery meets the legal threshold to be considered child sexual abuse, the IWF will work to have the imagery removed from the internet. They can also work to pre-emptively block the sharing of criminal imagery before it can be put on the internet.
