Qui est-ce qui m'a traité?

Question

Who insulted me?  Qui est-ce qui vous avez traité?  Who insulted you?  Traiter is new verb for me.

Accepted Answer

Bonjour Donald and Chris !Indeed, the verb "traiter" can be used to mean "to insult".
Here's where that comes from: the original sentence is: traiter [quelqu'un] de [quelque chose] = to call [someone] [something] 
but in speech, it's become common to imply the insult itself and to use "traiter" on its own, i.e. to call [someone], meaning to insult [someone].
I hope that's helpful!Bonne journée !

Answer

I would translate "Qui est-ce qui m'a traité" as "Who treated me." I am not familiar with traiter in the meaning of to insult.
