Why am i banned lmfao

This reporting system needs to be stripped down and be made new lol the fact that im in plat 4 and people are still feeding in my games is incredible. I got banned for flaming because i would be toxic to people who feed. I dont see the problem how being toxic can get you banned? You guys implement a muting system but still ban people? How does that make sense. I got banned after a game where my jayce mid laner ran down mid because when we invaded i got first blood AS A ADC. But no0o0o0o0o0o he gets to play after he feeds but i get banned for calling him a shithead lmao. Im only toxic when people feed in my game. You shouldnt have "bad" games in low elo. Its legit impossible, everyone sucks. I'd be high diamond if riot didnt put degenerates who dont take rank seriously on my team and hold me back.
