Q: 8) Who was responsible for the security breach? How did it happen? //Answer: A group calling itself Gnosis has claimed credit for hacking our servers.
I would say Gawker is responsible for the security breach.
Gawker is responsible in the same way that you're responsible that your house got robbed because someone found your hidden door key under a rock in front of your house.
