How would you react?

This has happened to me before, on more than one occasion. I would try contacting the person by private message, if at all. Sometimes I have just walked away if the drama gets too much. You have to weigh it out. Some battles are not worth the fight. After all, no response is a response.

I fully agree with what @CarolDM wrote. I would do the same and sometimes the best is not even to respond., just move on.

Depends on how trivial or serious the accusation is. If it's not that serious probably I would just let it pass. But if my reputation is at stake then maybe you can start thinking of something that would clarify why she is accusing you of that.

It depends on how I'm feeling at the time... If I'm tired and cranky, I'd send a pm asking how badly does the person want to be sued and suggesting publicly retracting the accusation MIGHT keep me from contacting my attorney. Of course, I'd also explain that I've already taken a screenshot of the accusation in the aforementioned pm.

It's better to send a private message to clarify the issue if she won't reply that means she wants war. You may report that to META or blocked her and her friends to have peace of mind.

It depends on how serious the issue is. If it's trivial, I would probably send private message to clarify. Otherwise, I may confront.

I personally would send a message, and ask that she retract the statement online. However, if she refuses, there is probably not much you can do about it. You said it was trivial so it might be aggravating, but letting it go is probably the best thing.

It depends on the situation. But the best thing would be to just not respond.

I'd send her a private message or just leave it. I wouldn't sue her. It's not worth the trouble or cost.

I would explain to clear the misunderstanding online. That would be straightforward

I don't know what I would do until it happened to me. I suppose I would send her a message to tell her she was wrong.

I will send her a private message. But if what she's telling the public is too destructive on my part, i will also make a comment on the same post to clear my name.

My facebook account is always public whenever i make post . I always post in facebook whenever people accuses wrong on me .

I always post in my facebook account whenever people accuses me wrong about me

I would send private message. Online could get very ugly.

Confronting the person is the first step

I suppose I would point out that it was a mistake. Then if they were part of a site I was on I would just block them,

It would depend on what was said. If it was something serious, I would definitely want a retraction.

If i met this situation,I will abuse back to the person who accuse me,I never take initiative to attack someone,but if only someone irritate me,i must fight back for sure.

We can make both of it I guess, it depends on situation and conditions, as long as the Respect over for all of it
