Worryingly, while the sites are intended for over 18s, neither conducted verifiable age checks.
With the online porn and dating industries exploding — the latter is worth £2.5 billion worldwide — experts are increasingly worried that extreme, and often risky, sexual behaviour among young people is being normalised by the internet.
Alone in a hotel room with a man she’d met only half-an-hour earlier, Becky Stevens knew it was too late to back out.
For six months, the 15-year-old had been chatting online to ‘Stuart’ after meeting him on an internet dating site.
Becky’s own descent into this terrifying world began at the age of 15, when her boyfriend, to whom she lost her virginity, dumped her and made cruel taunts about her size 16 figure.
But as an overweight, insecure teenager, she was desperate for the empty compliments that were showered on her in return for sexual favours — and the encounter was to mark the start of a five-year addiction to having sex with men she met on the internet.
Police warned that such incidents were a growing national problem.
Indeed, a recent study by the University of Plymouth found that there is a generation of young women whose attitude to sex is being corrupted through new technology.
Researchers at the university found that one in ten 16 to 24-year-olds have used the internet to set up one-night stands with strangers.
Half of those surveyed have carried out explicit sexual behaviour over a webcam, while 40 per cent of 11 to 18-year-olds questioned admitted knowing friends who engage in ‘sexting’ — sending explicit messages or photos between mobile phones.
