Paedophiles are stealing innocent Facebook family snaps to put on their own depraved pages on the social network.
The perverts trawl the site copying pictures parents have taken of their children and images youngsters have shared with friends.
Then they use them to connect to other child abusers around the world who post sickening comments underneath the snaps.
A Sunday Mirror investigation has uncovered paedophile Facebook pages packed with hundreds of pictures ranging from children as young as eight on beach holidays to “playful” underwear pictures posted naively by schoolgirls in their early teens.
Sprinkled among them were child abuse images on a string of pages with titles such as ‘Lolita’, ‘Jailbait-cuties’, ‘Naturalist kids lovers’ and ‘cute and gay boys’.
Following our investigation, last week Facebook closed down several pages and links.
We were contacted by a worried mum and dad of three children who stumbled across some of the galleries after following the Sunday Mirror’s investigation into paedophiles on Twitter.
Our investigators uncovered even more pages and pictures.
We then reported our evidence to the Internet Watch Foundation and called in child protection expert and former policeman Mark Williams-Thomas to analyse the galleries.
He revealed many of the cunning perverts stay one step ahead of the authorities by using stolen family and teen pictures which could not be classed as child porn.
“I have no doubt these pages have been created by paedophiles,” said Mr Williams-Thomas, who exposed Jimmy Savile as a predatory paedophile in a TV show.
“But they teeter on the edge of criminality so there are pages which are not illegal and Facebook can’t always take them down.
