Why did people have a different attitude with Jessie Slaughter than Amanda Todd?

When Amanda Todd's nude photo got posted online. People crucified her and commented on how terribly she was raised.

Jessie Slaughter's posted nude photos of her self online and everyone defended her and said it didn't have anything to do with her upbringing.

To Jessie she was only 12 and made a mistake and it wasn't her parents fault, but to Amanda her parents did the terrible job raising her and she was stupid for allowing her pictures to get posted online.

How come it was different for Amanda?
