I do love those who are brave to post pictures of themselves, and I hope the rules are respected, that nobody posts the pictures elsewhere. However personally my policy on this is, do not send a picture to anyone, that you would mind ending up on the internet for everyone to see, as sadly there is a huge risk of that happening, and it does not always have to be done maliciously by the person you sent the picture to, there are malicious phone apps and computer apps that scrape pictures from the computers they are installed on, among other data, and upload those to the hackers that made those things, so it is not even safe to take pictures and not sending them to anyone.
However I really hope that we will evolve as a culture to where what we do in our private lives stops being a thing anyone cares about, where we no longer think of women differently from men when it comes to sex, making words as slut and whore into positive words, said in love and lust, not as an insult but a term of endearment. We still have far to go on that though. There are steps back and forward on this going on all the time.
In that world having nudes online or sex videos, would not really matter as much, if anything someone trying to use them to hurt or intimidate would be the one risking their reputation, for being so backwards in how they see healthy sexuality, and trying to make consensual private acts into something wrong, and hopefully they will be shunned from doing such backwards things.
Still till we live in that world, I hope everyone will stay safe, and consider if they want everyone to see their pictures, I may be too paranoid and scared though, to share pictures of myself, but I think in recent years paranoid tinfoil hats have been proven more right than wrong.
