Toxicity in games and Riot going about it completely wrong
Since the majority of toxicity in this game comes from frustration and a feeling of helplessness do to the fact that you are literally stuck in games even when everyone is trolling or toxic. To punish frustration in a highly competitive game only causes more frustration causing more toxicity.
For example, one person has a bad game so everyone harps on him/her causing that person's frustration to escalate yet they cant put down the game like every other game because they are literally held hostage by the Leaverbuster system and have to play through the toxic game since most teams like that never surrender. Then after the match even after doing nothing toxic and being harassed and trapped in the game with these people the harassing party uses the automated report system (since the real tribunal has been taken down) to punish them and give them a warning simply for having a bad game since the automated system simply goes off of number of reports and not if the reports are valid. (So who are the real people that need punished?) Then that person frustrated by being harassed and punished simply for having a bad game goes into their next game so frustrated the first wrong thing turns them toxic and they repeat the pattern and on and on it goes.
So if Riot really wants to help fix toxicity they need to bring back the real tribunal ran by honorable players and make it easier for people being trolled to leave completely toxic and lost games. Giving people affected by the automated report system hidden punishments and long term strict punishments like this will accomplish nothing but making more people frustrated and toxic. Riots whole "I'm not sharing my toys with you cuz i don't like you" mentality doesn't solve toxicity it just shows us how toxic riot itself can be. Don't fight fire with fire Riot come on now your smarter than that.
