You don't know shit about the law, do you?
Let's take this a piece at a time. First, contributory negligence is a tort doctrine, not a criminal doctrine. Second, the doctrine of contributory negligence has fallen by the wayside in most American jurisdictions. It was a shitty doctrine used by wealthy industrial interests to avoid having to pay for the injuries they caused. Third, the doctrine of contributory negligence applies to situations where both actors are negligent. Guess what? The hackers who publicized the photos didn't accidentally plug in their own usernames and passwords and suddenly find themselves in possession of naked photos of dozens of women. They didn't accidentally publish those photos to 4chan and reddit. This was intentional conduct. Which means the doctrine of contributory negligence wouldn't even come into the equation. Fourth, the doctrine of contributory negligence was tempered by the "last clear chance" doctrine. That means that, as between the two parties to the civil suit, if both were at fault (i.e., negligent), then the one who had the last clear opportunity to avoid the accident is at fault. Here, the ones who had the last clear opportunity to avoid the "accident" would be the ones who hacked into the accounts.
People are also entitled to expect others to follow the law and to act reasonably. That's one of the perks of civilization. You seem like the kind of guy who believes that people who get hurt in car crashes should have known better before getting on the highway, or maybe that women have a responsibility to keep their ankles, wrists, and heads covered.
None of the women who were targeted by the people who did this consented to have their pictures publicized. That's really the end of the blame analysis.
