Punishment And Fairness

My opinion on this, Is it is way to easy to report another player. Like for example the enemy team could be feeding alot the whole game, But if the person on the opposite team says anything bout them feeding or if the enemy gets a attitude because their losing. And says something like "Blow me" Or "You play with a helmet on because you only play meta" Nothing happens but on if the other person says anything back to respond. their the ones getting either chat banned or banned.. To me its not fair to the people who try to not be toxic but they get punished. My point is its way to easy to report someone on this client way too easy.. Its like I'm playing runescape. I understand if your toxic you must be punished yes, But when its more then just one doing it. don't only punish the one you think is being toxic. You punish all being toxic whether or not they started it or not.. its fair and right now "Riot" you're not being fair to everyone... This is all..
