Relating a Story While Concealing Names

If it is an unpleasant story and there is no information that could identify the people involved, then it is not backbiting; but if it will provoke trouble or lead to bad consequences, then mentioning it is haram for that reason, even if it is not backbiting. 

And Allah is the Source of strength. May Allah send blessings and peace upon our Prophet Muhammad and his family and companions. End quote.
