Banned for being reported by trolls? [PROOF]

I was banned a few minutes ago, PERMANENTLY. Now in the past I have been reported for my foul language and see why. I have been good and have not been talking in the same manner. Yet, like always there will be others who don't. In most cases when trolls report Riot will just ban without investigating, if this is wrong please correct me but seconds after my game I was banned. If you read the chat log you can see I was trying my best to not offend anyone, simply replying to questions being asked by my team and others. If there is anyway Riot can check my team mates chat this game they would see a Rengar by the username CrazyAwesome69 harassing me the entirety of the game telling me to go adc when I called mid in pregame lobby. A Nidalee didnt even call mid yet said "im going mid" and continued to go mid. I stood my ground asking for her to go bot or top and she fed my lane then left. This is when Rengar stated to report ME. I then told him that Nidalee was trolling and left me in lane with a fed Lux. Rengar continued to bash me and a Leona jumped in agreeing with the Rengar that the whole situation was my fault. I kept my cool and continued to play. Yet I was reported anyways by both, maybe all three for who knows what, going mid when I called it? Nidalee was also reported from what I heard but who knows. Please check into the chat logs and not just ban off troll reports.
