Publicly humiliating people on social media

𝑔𝒶

There’s a girl I went to high school with who is kind of “Instagram famous” in the college community. So she has a decent following.

Now whenever someone (mostly males) does something wrong to her like telling her her body looks photoshopped or sends her a not so nice message, she screenshots the message they sent and their profile so people know exactly who they are. It’s caused some problems with her friends and followers going to that persons page and attacking them.

Are things like this ever okay?
