@YoureAGoodManArthurMorgan - just because you don't think leaked nudes should be any big deal to the woman whose pictures are leaked, doesn't mean everyone agrees with you - as @mlc0's post demonstrates, leaked nudes can have a massive effect on someone's life.
Even if you are right when you say "It's surprising how many people think their lives would be ruined if a nude pic of them got around. I doubt you're of such importance that anyone would recognise you, let alone care." - that's not the only thing that matters - the reaction of the woman concerned matters too, and if she feels violated, humiliated, upset about nude photos of her circulating online, she has every right to feel that way.
@Stuffisperplexing - I think it isn't about women being embarrassed about their bodies (though as someone who has been overweight her whole life, I really DO understand that) - it's about consent and the betrayal of trust. A woman sends some pictures of herself to one person, for their eyes only (and even if this is not explicitly stated, surely it should be understood by the recipient), and for whatever reason, they share the picture.
She has explicitly consented to the recipient of the pictures seeing them, but there is no consent for other people, whether she knows them or not, to see them. She has trusted her partner with intimate images, and by sharing them, her partner has broken that trust.
I think that these are major issues.
