Can you be more specific on why you think the people who sent emails are "evil" and deserve to be judged? And I'm talking about moral aspect here, not legal.

> They are clearly nothing but malicious, bigoted and evil.

Try to look at it this way. Jane Doe lived in a society (family, coworkers, friends) where she was respected and was considered to be good, ethical and honourable person. At the same time she wanted to play in porn. Maybe because she was just curious, or being filmed during sex was her secret fantasy (you know, it can be a big turn-on to imagine other people watch your sex), or she wanted some quick money, or something else. The problem was that playing in porn was unacceptable in her society. We don't know why they thought so, maybe their perception of sex was different from hers and they didn't like people to to it publicly, or they also had this fantasy of playing in porn but never had courage to actually do it, or something else. Whatever were the reasons of the society and of Jane, I don't judge them.

So Jane encountered this dilemma. She wants to keep the respect she has in the society, and she wants to play in porn -- two wishes are incompatible. Jane is smart, and she decides to play in porn making sure the society never finds out. It looks like a win-win sutuation for her. I hope, she realizes that there's a risk of being caught at this point.

People who film the porn promise Jane not to publish the videos online. And they break their promise. This is obviously a "bad", "evil" and immoral thing to do. I think we all agree that not keeping our promises is immoral.

Someone encounters Jane's video online, and assumes that the society Jane lives in is very likely to consider this immoral, and Jane has probably played in the video secretly. And this person has the choice: to report Jane and act in the society's interest, or not report Jane and act in her interest.

I don't think we should be concerned here with only Jane's interests, people around also have their wishes and feelings. If she's a teacher, her students parents may not want a porn actor to teach their children, and that's their preference which, I think, we should respect too. Her parents may be traditionalists and they may want to know if their daughter is doing something that they consider immoral. Jane is not the only person who has feelings here. So why shouldn't the person email Jane's friends and parents and tell them that she's lying to them?

You might notice that I'm writing this comment from an account I just created. When I did this I also had a choice similar to Jane's.

Most of the people around me now are strongly liberal. And when we discuss something related to women, sex and slut shaming, it's not very favorable to express anything except sorrow for women and judgement for anyone who caused them trouble. But I have many other thoughts on this subject (like the ones I expressed above about Jane), and I'm afraid my friends will not like this. So I did the same choice Jane did, I decided to do what I want secretly and anonymously.

And if somebody finds out my real name and decides to inform people I know about this terrible sexist pig they invite to parties and spend time with, I won't judge that person. They're just acting in other people's interests, not mine.
