Autoban System Could Use Some Tweaking

Putting your account in the hands of people in the league of legends community is just asking for people to be unfairly banned. I received a 14 day suspension after I may have been somewhat unreasonable and rude, but upon returning, I decided to turn a new leaf and change my mentality in games. Surprise surprise, my first 5 games were blow out wins and I didn't receive a single report. On my 6th game, I played with a warwick who admitted this was his first time playing a ranked game. He came mid to gank my lane, but waited until the opponent was nearly under her own tower to ult her, which let her escape. I asked him why he waited so long to ult, and told him it wasn't a great gank, and him and his duo went on a rampage, begging everyone in the game to report me for being toxic and flaming, meanwhile they were flaming me for being 1-3, calling me a feeder, troll, etc. Not even 3 minutes out of this game at the end, my account was perma banned. How am I supposed to reform when I get automatically permabanned for reports that aren't accurate? What is the point of the 14 day suspension warning if you aren't given a second chance to reform, and are simply perma banned from the first set of reports that you get?

I hope to hear a legitimate response/explanation for this.
