Children who use technology may unwittingly share information that can put them in danger. In 82% of online sex crimes against children, the sex offenders used social networking sites to get information about the victims preferences. And the anonymity of technology can also make it easier for people to bully others online. A quarter of teenagers say they have been bullied either by text or on the Internet. Sexting is another high-risk behavior of concern, with 24% of teenagers aged 14 -17 have participated in some sort of nude sexting.
