You’d be surprised. Some people do it for money, they don’t even know the person, other people do it for the fun of it (because their bored) or just to see if they can get away with it. It might not even be anyone he knows or any of you guys calling for him to post it. It could just be someone randomly browsing the website (which if they were without an account, why here specifically? Just go to twitter or Facebook, theres more targets and probably just as much easy prey like most people here) who happened to see it. And even then, you can find it in archives most of the time even after it’s deleted. He’d need to link the page in a comment, delete the image after a couple people see it, hope no one saves it and posts it again, and prey to god his info doesn’t get stolen.
