The Ofcom report “Children and Parents: Media Use and Attitudes Report”  (November 2015) writes: “While children’s contact with people not directly known to them online is not necessarily risky, it has the potential to lead to risky or unpleasant experiences. Less than one in ten 12-15s (7%) say they have added people as ‘friends’ to address lists or contact lists whom they have only had contact with online, while 4% have sent a photo or video of themselves to someone they’ve only had contact with online, both measures unchanged since 2014. Four per cent of 8-11s and almost four times as many 12-15s (15%) say they chat with people they don’t know when playing games online.”
