how can people be like this ???

last match i played a normal ranked match with normal people atleast that was what i thought but after a couple of mins our adc vayne said that his support is bad and he just went feeding without a reason and he kept flaming all of us but i didnot give up i did my best and i won jungle and we won other lanes and won at the end i just wonder why would be people like this in this community how can someone like that doesnot get punished he was super flamer and a feeder he probably got 7 report from us and from the enemy team ,, people like this doesnot deserve to play this game,,, i lost faith in humanity ,,,, Btw iam not in low divsion (bronze) and he wasnot either
