I am in a group chat of many classmates who are pursuing the same degree I am. I sometimes poke fun at one of the girls in the group chat because I have known her for a long time. Tonight she uploaded an embarrassing picture of me from middle school into the group chat in which many of the class mates that I typically work with professionally can see. Will this hurt my reputation and why would this happen to this extent? I have never publicly humiliated anyone like this.
