Even though I have long participated in MySpace and Facebook, I have to admit that I worry about the judgment of young teens and tweens as they carve out their own corners of the Interwebs.

As a reporter I have come across horror stories of bullying, abuse, and even child predators on MySpace. The suicide of Megan Meier after she was bullied via a faux MySpace account cast a harsh light on the darkest dangers of these social networks.

Now it appears that teens are filming fights and posting them on YouTube and MySpace. That was the apparent motivation in Lakeland, Fla., where six teen girls were recently arrested for luring a former friend into a home and beating her unconscious:

For 30 minutes, six girls ganged up on a classmate, slamming her head into a wall and taking turns pummeling her and videotaping it all to post on the Internet. And when they were arrested and were being booked into juvenile detention, they joked about not being able to go to the beach, a Florida sheriff said Tuesday on TODAY.

The vicious attack was supposedly in response to slurs and insults the victim had posted about them on MySpace...

Officials released three minutes of the 30-minute video that show two of the girls taking turns screaming obscenities at the victim between attacks with their fists, while the others watched and taped the attack. They also challenge the victim to fight back, which she does not do on the video.

The 16-year-old victim suffered a concussion, and has hearing loss in her left ear and some loss of vision in her left eye, Judd said.

Six girls under the age of 18 will be tried as adults on charges of battery, false imprisonment and kidnapping. Because kidnapping is a first-degree felony, they face a maximum sentence of life in prison. Their arraignment is scheduled for today.

The most disturbing aspect of this story is the lack of remorse displayed by the girls, who while in custody joked about not being able to go to the beach; one girl asked a guard if she would be out in time for cheerleading practice.
