chat restricted for saying "bronze 5"?

I was just hit with a 10 game chat restriction and honor penalty to level 1 because I responded to two people in my games hurling homophobic slurs and insults at each other and myself by calling them bronze/noobs. Really? What is the difference between "banter" or "competetive bs'ing" and calling someone bronze or a noob? Both of these terms and worse gets typed into live games being streamed on twitchtv everyday being watched by tens of thousands of players, and I have the twitch clips to prove it. Are those people getting chat restricted? No? Makes sense. I even got an instant feedback report saying that at least 1 of those 2 people who were flaming in my game got punished as well because I obviously reported them for constantly spamming profanity. I did not say a single word or acronym of an insulting nature other than calling them bronze and noobs. I know I was not in the right either by becoming involved in those toxic individual's argument, but is it really fair to punish me for simply calling someone a noob or an actual rank in the game that they are/have been? Is it bannable to call a diamond player a 'diamond 5' then? I don't expect the penalty to be reversed because I know you guys never do that, but can I at least receive clarification or a list of prohibited terms so that I can actually chat without getting banned? If I am going to get banned for calling a gold 5 player a 'gold 5', I may as well uninstall now and spend my time and money on a game where facts aren't considered insults.
