How dangerous are networking sites?

For 13-year-old Missouri girl Megan Meier, the bullying she received through MySpace, which she believed was coming from a boy in the neighbourhood, appears to have driven her to take her own life.

In fact, while Megan thought she was being abused by 16-year-old Josh Evans, she was actually talking to Lori Drew, the 49-year-old mother of one of her former friends who, it is alleged, had set up a fake profile to taunt Megan.

Ms Drew is now standing trial on computer fraud charges.
