A breed of upstart apps is taking on an internet function that might seem unneeded or even ill- 【小题1】: helping teens talk to strangers.

Branded as “social discovery” services, these apps pitch themselves as alternatives to outlets that already specialize in online connections, like Facebook and Instagram. They say they are better at helping young users meet like-minded people outside their existing circles. And they say they have 【小题2】, such as separating users by age and using artificial intelligence, to protect against the inappropriate or unsafe behavior that has caused problems to previous attempts to connect young people online.

Their user numbers suggest that, whether they succeed in striking the right balance, apps like Yubo and Hoop are 【小题3】 into a need among teens and 20-somethings for new ways to branch out online. “There is no place today to socialize online,” says Sacha Lazimi, the 26-year-old French co-founder of Yubo, which connects strangers with messaging and live-streaming.

But some of these apps have also been the subject of safety concerns. Yubo has also faced its Own safety challenges. In Florida, law-enforcement officials say they arrested a man who 【小题8】 lured(诱骗) a teenager through Yubo.

In a statement, Yubo said that the prevention of child abuse has been a key 【小题9】 for the past three years. “Yubo recognizes its responsibility in protecting young people using its service and has gone far beyond many of the main social-media services.”

“However, actually teens are 【小题10】 with more to protect themselves than expected”, says Dr. Hinduja. “They are doing something to keep themselves safe or we would have strikingly more victimization than we do.”
