A lot of people on the internet including the Muslims, are miserable people and they take it out on each other by being unkind and judgemental. I believe there should be no reason for Muslim men to have commented on the photo. If they felt this photo was compromising, lower your gaze applies on social media as well. If you wouldn't speak to the sister if you see her in the street, don't do it on the internet. And when you do it, don't be disgusting with your words. They should have left it to the sisters to speak to her. There are plenty of Muslim women in the quotes advising her.
She posted this which is very interesting:

So now she doesn't want to associate with Muslims. I did see that many Muslim men and women came to her defense, but it seems like she took the negative comments more to heart. There are also islamophobes in her comments telling her to leave the deen. And it's possible she might. I hate to say it, but this situation was a test, of the strength of her deen and a test of the aklaaq of the Muslims who interacted with her. Allah knows best.
