Wait do we know for sure that this is a "hack" and not a Brianna Wu tier publicity stunt? Who the forget would want her nudes in the first place? Why would she even take the pictures in the first place (this might just be me wondering why anyone would be stupid enough to take naked pictures of themselves in the first place).
Celebrities in general are:
1) Dumb enough to take pictures of everything with their fancy phones. Probably set up to cloud everything automatically.
2) Dumb enough to not know how to protect their accounts.
3) Popular enough to be targeted.
It's not a matter of people wanting to see her. It's that people want to spread her stuff because they don't like her.
