Reported for language.

so i was in a normals match, i was actually being probably the best sport on the team, and after the game, i received a warning for bad language. i can say i was the most polite person on our whole team, because when we started in the champion select, three people including me said mid,then one of them took Azir even though he was not mid, he asked where he should go, i politely said "go support" and then in the game, he dc, then came back apologizing for his pc overheating. i was the first person to say "np it happens. you came back at least" and then we continued on, i kept saying good job when we would do teamwork kills, then enemy team surrenders, i give awards for teamwork, i give an honorable opponent to the one i fought in top lane during the game. and i say gg and all that. leave the after game chat to see i've been reported for bad use of language. is there an admin or somebody i can talk to about this? i'm known by quite a few people to be a good sport, and i don't know if it's worth being a good sport if i'm just going to get reported for this kind of thing anyway.
