I challenge Riot Games

Ok so I understand that people probably bitch and complain a lot about this but I think it is completely asinine that you can get banned for leaving a game. I've left games yes because I have been angered at losing, I'm not saying I'm above that, but I should not have to put up with being harassed by other players. If I go to adc and someone just comes down and purposely feeds, takes farm, whatever than harasses the team about it, I shouldn't be forced to sit there and be completely miserable because I'm afraid of being banned. And I know what you're thinking, oh you had to leave multiple times blah blah blah, ya obviously but we all know how people are on this game. It doesn't just happen once or twice, it happens on a constant basis. Nothing is ever done about it. I should never have to put up with it from an online community who Riot, supposedly, tries to keep clean and user friendly. Its not ok and I shouldn't have to suffer my account being banned because I will not sit here while people ruin this game for me. No one should, Ive won more games and have more fun when people who are causing problems leave the game as opposed to them staying and feeding or intentionally ruining the game for the rest of the community. I challenge Riot if you truly give a shit at all about the game, community, player, etc. to figure your shit out and think of a different way to handle these kinds of situations because frankly I don't think what you're doing now is the solution. Rant over.
