DALLAS, Aug. 9 (UPI) -- A 9-month-old social networking site that attracts teens and promotes anonymous, cruel postings contributes to cyberbullying, experts say.

The Dallas Morning News reports visitors to Formspring.me, nearly a third of whom are age 17 or under, ask cruel questions anonymously or post comments that have included: "Go kill yourself and make the world a better place," and "Is that you in your profile picture? It looks like a dead old man."

The site could make cyberbullying, already blamed for three deaths this year, more dangerous because it's anonymous, critics say.

"This site is essentially an anonymous way for teens to bully each other and the danger in that is it, over time, becomes overwhelming," said Missy Wall, director of Teen Contact, a Dallas-based teen hot line.

"Cyberbullying isn't new, but this sort of copy-paste teenager impulsiveness causes kids to make an account to try to be popular."

Formspring officials say the Web site offers another form of connection for teens, not dangerous simply because it's anonymous.

"All of our users want to have a public platform for them to feel comfortable asking their friends questions or even asking their boss a question without the ramifications," Formspring spokeswoman Sarahjane Sacchetti said.

Formspring says the site has 12 million users and more than 50 million visits a month. The site says it is designed to give users a chance to ask questions, not always anonymously, about anything.

Cyberbullying experts said online hostility can start as young as age 7.
