The problem, it seems to me, isnt with the advice, or even the inherent blame that in some measure goes along with the advice. Rather, its with two related things about how the advice is given.
First, much advice of this sort wrongly fails to acknowledge that the advice can be costly to take. No, no one has to take nude selfies or e-mail them to their lovers. But avoiding this behavior for fear that youll be hacked means accepting a limit on ones autonomy generally (and the autonomy of ones erotic life in particular). Likewise, avoiding going out alone at night at least in certain places for fear of being raped means accepting a much greater limit on ones autonomy.
People who value freedom dont like that. People who value freedom shouldnt like it. Making it sound like the person is a fool for not limiting her own freedom this way ignores that cost to freedom.
Second, and relatedly, its one thing to implicitly fault someone, and another thing to do so more expressly especially when that person has just been victimized and deserves our sympathetic outrage (or just sympathy, if the incident is an accident and not a crime). When a friend is in the hospital after the car accident, thats a bad occasion to tell people that he could have been safe and sound if hed only worn a seat belt.
Likewise, when someone has been raped or beaten, thats a bad occasion to give people useful advice about not being alone in dangerous places, or about not dating the ex-girlfriend of a notoriously jealous thug. (I deliberately give here examples of behavior that is in no way morally culpable, that in a just world everyone should be free to engage in, and that can only be avoided at substantial cost to ones freedom but that, in our world, is still safest to avoid.) Now, the release of nude photographs isnt quite in the same category as a brutal physical attack, but its still pretty bad stuff; and chiding the victim strikes me as similarly out of place there.
