(CNN) - Brandon Turley didn't have friends in sixth grade. He would often eat alone at lunch, having recently switched to his school without knowing anyone.

While browsing MySpace one day, he saw that someone from school had posted a bulletin - a message visible to multiple people - declaring that Turley was a "fag." Students he had never even spoken with wrote on it, too, saying they agreed.

Feeling confused and upset, Turley wrote in the comments, too, asking why his classmates would say that. The response was even worse: He was told on MySpace that a group of 12 kids wanted to beat him up, that he should stop going to school and die. On his walk from his locker to the school office to report what was happening, students yelled things like "fag" and "fatty."

"It was just crazy, and such a shock to my self-esteem that people didn't like me without even knowing me," said Turley, now 18 and a senior in high school in Oregon. "I didn't understand how that could be."

A pervasive problem

As many as 25% of teenagers have experienced cyberbullying at some point, said Justin W. Patchin, who studies the phenomenon at the University of Wisconsin-Eau Claire. He and colleagues have conducted formal surveys of 15,000 middle and high school students throughout the United States, and found that about 10% of teens have been victims of cyberbullying in the last 30 days.

Online bullying has a lot in common with bullying in school: Both behaviors include harassment, humiliation, teasing and aggression, Patchin said. Cyberbullying presents unique challenges in the sense that the perpetrator can attempt to be anonymous, and attacks can happen at any time of day or night.
