PARENTS have been urged to talk to their children about sharing information online after a survey exposed the ease with which youngsters can access unsuitable content.

The NSPCC will today launch a new campaign to advise parents on how to address the issue after a panel of more than 500 parents from Mumsnet reviewed 48 social media websites and said all those aimed at adults and teenagers were too easy for children under 13 to sign-up to.

On more than 40 per cent of the sites, the panel struggled to locate privacy, reporting and safety information.

The charity asked just under 2,000 children and young people which social networking sites they used, then had parents review 48 popular social networking sites, apps and games including Sickipedia, DeviantArt and F my Life. Three quarters of parents were able to find sexual, violent or inappropriate content on all three sites within half an hour.

The survey found no unsuitable content on entertainment sites for younger children such as Club Penguin, Moshi Monsters, Popjam and Bearville.

NSPCC Scotland says its helpline regularly hears from children and adults who are worried about online safety. One adult from Aberdeen called because she was worried about a young teenage girl who was in a relationship with an 18 year old. "I saw an image of her performing a sex act that had been posted online," she said. "You can clearly identify that it's her and the image seems to have been widely shared. I'm really concerned for her."

The NSPCC has used the reviews to create an online guide, Share Aware, to help inform parents about the risks of different social networking sites used by children.

Matt Forde, NSPCC Scotland national head of service, said: "Children are taught from an early age that it is good to share but doing so online can be very dangerous. This Christmas many children will have been given a smart phone, a tablet computer, or a games console. So it's the perfect opportunity for parents to have that important conversation about who they are talking to and what they share when they socialise online.

"We know that children do take risks online, sometimes without realising it. Our Share Aware campaign gives parents straightforward, no-nonsense advice that will help them to untangle the web and feel confident talking to their children about online safety."
