Yeah I've read about this before (a few years ago) It's pretty disturbing and as I parent I think it's important to have a good line of communication with your children and perhaps warn them about the danger of stupid "games" like this. What's going on with kids these days anyways?!?
When I was that age I was busy playing with my friends and watching cartoons I wasn't intested in a "thrill buzz" Are these kids bored?
