This week another teenager committed suicide in the welsh town of Bridgend. She's the seventeeth to take her own life.
The police have said they think the internet played no part in the deaths.
Two columnists address this.
Libby Brooks in the Guardian says the rush to blame the Bridgend deaths on social networking reflects adult ignorance of the role of technology in young lives.
"Children and young people have always sought spaces beyond adult surveillance. It would seem teenagers are moulding new media to meet their needs, rather than being moulded by it, as feared. At a time when children are more captive than ever maybe we ought to celebrate the way they have ducked under the wire and created a whole new version of literacy."
Bel Mooney in the Mail asks: "What if the problem is merely adolescent alienation in an increasingly pressurised world?
"All the evidence points to the conclusion that life is much tougher now for kids. The UK came a shameful bottom of the pile in a recent survey of life satisfaction of children in 21 developed countries. Last year, no less a body than the Institute of Psychiatry reported that the number of children with emotional and behavioural problems has doubled in the past 25 years."
