Instant Feedback Team Chat/All Chat

Hey. I was in a game recently that in team chat someone said f-word and my girlfriend(very much gay, obviously) asked if she meant "f*****" because she didn't understand what they meant. We were in a premade team of 5, and no one reported her from our team. Then she got 14-day ban(first offense) because someone from the enemy team reported her for no reason, and as reason it was showing the chat that she said "do you mean "f*****" " in team chat. Wouldn't it make more sense if someone from the enemy team reports you, you get instant feedback based on all Chat and not team chat? This is completely uncalled for, and I sincerely don't think this is how the system is intended to work. If no one reports you, you probably did nothing wrong. If someone from the enemy reports you, the only thing that matters should be what you said in all chat. Not to mention context is also important, but I get that they think some things shouldn't be said in any context.
