Should the parents have watched a little more closely? Sure.
Again, you cannot place the blame on any one person/group of people.
The parents most likely feel guilty... they may feel as though they weren't proctecting their child. The world is so big, and the number of child rapists is so daunting, that they chose the easiest and nearest target: MySpace. It is indeed the scape goat. That's why I said in my last post that shifting the blame is a bad idea... That means shifting the blame to anyone, even the parents. ^_^
To be honest, parents cannot be there all the time.
I did some stupid things when I was a teen, and my folks couldn't be there 24/7. And until you have kids of your own, it's hard to judge. Because I know it has to be hard! ((I look back and the grief I gave my mama... OH BOY! And I wasn't even that bad! It has to be hard!)) ^_^
