It's hard to tell and you can only tell case by case.

As a false accused myself it's hard to fight back once you are in that position. Only thing I did was rejecting her. My only luck was that I had the whole Whatsapp converstation on my phone and the female had a very very edited version posted. I lost alot of friends because her revanche actions. If i didnt have to, i would also deleted everything to shut up people and go on with my life.

It's hard these times to what is truth or not and way to easy grabbing a torch to burn someone.
