The real reason league is toxic. and why no amount of carrot and stick will fix it
League is split into several camps. and riot is only acknowledging a few of them. and some are more toxic than others. but it all stems from the fact they dislike each other and/or dont feel heard. and riot refuses to deal with them. and just throws out bans when people get enough valid reports
The "back in my day" crowd : season 1/2 vets mostly adults many of whom grew up in an age in gaming where flaming was considered ok as long as you werent shouting kys or racial slurs and even trolling was tolerated as long as you didnt do it too much. "see leeroy jenkins" and because of this fact. many loyal players have had to have one or more accounts permabanned due to the strike system when in the previous system probably wouldnt have even gotten a chat restriction simply because they are unable to adjust to new norms.
the safe spacers : people who believe anything negative or even simply not positive. should be simply eliminated. and shun reform in favor of zero tolerance policies strike systems. and witch hunts. sadly. riot agrees with them just not publicly
the tweenies: 12 year old preteens who honestly have no business playing a game for adults. grow up in an age where participation trophies are the norm. think its fun just to f*ck with people because of thier own insecurities and that intentionally ruining someone's free time is ok because "hey its a video game. these people need a life" even if they dont do it every game. theyre unpredictible. and if they dont troll often enough they might not even be punished
the competitors. everything is a competition. they dont play the game to lose. whether or not they're actually good is another story. are prone to raging due to trolls or even just bad players because in their mind its not thier skill holding them back. love the game very much but end up either being cast out or permabanned due to the inability to stop themselves from typing
the cultists : people who accept anything riot says as gospel. regardless of whether they actually agree with it personally.
