Gambling websites are targeting children by exploiting loopholes in advertising laws, a new study warned. Eight in 10 teenagers are involved in some kind of gambling, with 10 to 15 per cent of minors at risk of developing serious gambling problems, the research found. The study by Queen Mary University of London (QMUL) and City University London found bookmakers were getting around new watershed laws by targeting children on social media. Professor Julia Hörnle, Professor of Internet Law at QMUL, said in an article for the Daily Mail: “Gambling advertising is restricted if it targets children. But what if the advertising targets adults, but is equally appealing to, and consumed by, children?”
