Does it really matter though? "Well you see, they didn't actually see you naked, it was just a photorealistic approximation of what you would look like naked".
At that point I feel like the lines get very blurry, it's still going to be embarrassing as hell, and them not being "real" nudes is not a big comfort when having to confront the fact that there are people masturbating to your "fake" nudes without your consent.
I think in a few years this won't really be a problem because by then these things will be so widespread that no one will care, but right now the people being specifically targeted by this must not be feeling great.
Is that safe though? After seeing that XKCD I also thought it would be a good idea but then read that using passphrases is even worse because brute force attacks often use dictionaries as well to test word combinations, so one should use scrambled characters, just long enough to resist brute force.
