I agree with mp5stab. It’s one thing to fantasize about fictional characters or those who volunteered, but it’s a completely different matter to post photos of random person for sexual gratification without their consent.
It’s morally wrong and I believe this community is already prone to draw prejudices even without such things.
(You can call me a hypocrite if you like, as I already posted such a comment in this thread. I didn’t realize it was a random photo at that time but I can’t delete it now, so I won’t complain if someone would blame me for that.)
