I think that Robert should not do the prank. Why because he can get in serious trouble. The school can contact the police and he can go to jail. A norther thing is that if the school finds out it was him they can expel him from the school. So thats why he cant do it! 

I  think that what the teacher said yesterday was correct. Why because the Internet has a lot of bad things. I think that a lot of sexpredetors have fake identities just to get to kids. I specially don't have a my space well I did have one but I delinted because there was allot of rumors and people that want to harm you harm you will tell you to leave  your house and then they will kidnap you. Never put information about you. The Internet can be deadly.
