Would you know what to do if you shared intimate photos online - only to find them being published without your consent, or used to blackmail you?

READ: Investigation: Number of boys blackmailed over nude images online is soaring
The Internet Watch Foundation has seen an 800% increase in incidents in the last year alone.
90% of the incidents involve boys, with the majority of victims aged 16-17.
You can have nude images removed from the internet
There are steps you can take if it happens to you.
The IWF works with the NSPCC on the Report Remove service.
This software allows staff at the Internet Watch Foundation to effectively put a digital fingerprint or "hash" on images they deem to be potentially abusive, and stop them being shared across internet servers.
It means images reported by young people are much less likely to be shared on mainstream platforms.
IWF CEO Susie Hargreaves told our investigation: "Once an image is on our hash list, which is deployed across the world, every single time, on the major platforms, that someone tries to upload that image or share it, it will hit our hash list and it won't be uploaded.
"It does give huge amounts of hope to young people.
"They know they can report, it's total non-judgmental.
"We want them to know they are victims and there's help out there."
