"These impersonations are almost always kids impersonating other kids," she said. "I see 200 cases a day of kids pretending to be the bullying victim and making allegations about their promiscuity, for girls, or homosexuality, for boys."
Imposters have been involved in a series of serious cyber bullying cases, including the 2006 suicide of Megan Meyer, a Missouri girl who hung herself after being bullied by a teen boy online. In reality, that boy was the middle-aged mother of a girl with whom Megan went to school.
When Collin's parents learned about the fake Twitter feed, they contacted local police, his school, the user behind the @CollinMcKechnie account and the fans following him.
Once exposed, the imposter quickly came clean.
"I feel wickedly guilty (and wickedly proud) and for what its worth, i'm sorry. All this coming from a big fan of Collin myself," he tweeted.
"I know you all gonna hate me for this, but you have to admit I was one one of the top 10 twitter impersonators of all time," tweeted @ColinMcKechnie. "I urge you to go out and impersonate an upcomer [sic]. What an experience its been."
When contacted by ABC News, the impersonator responded via Twitter: "I'm gonna deactivate as soon as I get my hands on a pc. Soon I promise. I dont knw hw to find the deactivate option on my cell phone lol."
He did not answer any questions about his identity. He later changed the name on the account from Collin MacKechnie to the Collin MacKe Fan Club.
Twitter would not comment on the details of Collin's case. However, company spokesman Jim Prosser told ABC News that Twitter has a policy that bans impersonators, excluding celebrity parody accounts.
He said the company investigates all complaints and deactivates those found to be fake.
As of Thursday evening, the @CollinMcKechnie account was still active.
