I see both sides to this coin:
Side 1 - You play with fire, if you get burned.......sometimes that's a result of playing with fire. I have zero respect for cheaters and as such no sympathy (even in this case).
Side 2 - I believe people have a right to privacy, and hacking this site is ILLEGAL and akin to going into the business/house and finding info and threatening to publish it. The information should have never been obtained in the first place.
The amazing thing about this story is that you just KNOW there will be some famous people on that list. Also, there will be families destroyed by this publication.
