Toxicity is Only a problem because "We" allow it to be a problem, and removing it instead of---
overcoming it, lowers the skill level of the playerbase.
(Note that this is all referring to verbal "toxicity" that does not register as an "Extreme" case)
"Removing" toxicity, essentially removes the "opportunity" for you to improve as a player mentally
I continue to disagree with riot on their stance on toxicity. Instead of trying to Remove and ban all toxic players they simply need to decrease the relevance of toxic players, Overcoming weak traits of the mind is part of a competitive game, overcoming toxicity as a player is the only way to improve past simple mechanical skill, and game knowledge, trying to remove toxicity in itself will create nothing but tension within the community, and a Weaker playerbase/region skillwise.
The strong willed, will mute
There is never a reason to afk from game, and toxicity is not preventing people from climbing, there is a mute button for a reason, and the only problem is that riot does not enforce the usage of the mute button, they in fact enforce "not" using it, they can create an auto ban system so there is so much more they can do, Pressing mute is not only a sign of a player actually trying to improve but proof that they have strengthened their own mind, a weak player will not press mute, take abuse and then complain that they were abused looking for others to fix a problem that was never a problem, you cant climb, because you look for excuses to why you cant climb.
What could riot do?
Some fixes for this for players incapable of Doing what it takes to focus on themselves. Automatic mute on people who use to much profanity, escalated chat restrictions leading up to "chat" bans, "chat ban mode" where a person can choose to only have 1 chat permission per min to invoke less volatile speech pattern of their own accord. Reporting a player automatically mutes him for the future. No chat mode, where you can just disable chat as a whole if you choose. Lest we forget that we also have the option to block all chat, we also have the option to keep on a profanity filter.
You "Chose" to see, you can Choose to close your eyes
The issue with this community is that People "Choose" to open their eyes, and their ears to all the good and evils of this world and They are to fragile to exist in that "awakened" state shall we say. when they meet up with the negative, the blunt, and the Cruel mindsets, their glass mind that was not ready shatters, and then they blame the world for being the world, and look to their adjudicators to "Fix" a "problem" that only exists because they "allowed" it to exist. You want a solution?
What "Else" could riot do?
Change the report options, remove the stupid shit like unskilled, and simply have, Racial/homophobic slurs, Negative attitude, Afk, Intentional feeding/Greifing, cheating. and that should cover it.(somewhere in their there would be something for people who wish you physical harm one way or another)
It is probably just as simple as this Now for almost every single report, you have your system check people, and for the people who continually report people for "negative attitude" all riot has to do is have the system automatically re-enable everything they turned off that allowed negative attitude to effect them, re-enable all chat mute, and profanity filter, and then when that person feels like they are ready, they can turn it back off. And every time they start to repetitively report people for negative attitude it re-enables all the shit they turned off again. and then at the same time a person who gets reported a number of times for negative attitude, may need to be chat restricted, leading up to a chat ban worst case scenario,
"Why even punish them you say? well its not really punishment, its a lesson, Exclusively for them"
Simple. Verbally toxic "hot headed" players are also weak minded, on the reverse side of the spectrum to the "Glass minds". They allow themselves to be swept up in a tide, and instead of swimming against it, and choose to simply flail in the water grabbing anyone around them, to try and drown everyone. If you want to go in the ocean, first you need to learn to swim, Chat restrictions, are your lessons, and everyone knows, when you fail in your studies, you simply need to be retaught the same lessons over, and over, and over, and over again, until you learn how to swim properly.
Just. Like. That.
You have created a community of players with thicker skin, because they no longer "need" to overcome the Barrier that is a weak mentality. You have Taught them how to overcome it, and you have Taught Both sides of the spectrum, how to meet in the center". We call the center, The enlightened members of The Higher Competitive Society. In short "high elo"
Is being an adult acting mature? or is it being mature enough to not let immaturity Effect you
Their are sooo many options to combat toxcity other than banning people permanently, or at all, You say people have to act like "adults" but lets try to remember the very simple lesson "adults" have tried to teach us since we were 4 years old "sticks and stones".
are you really that vicious? You may have hurt feelings, but just remember that when you ban someone for hurting your feelings you are collectively taking away everything they worked potentially "years" for, for a moment of superficial pain they caused you.
Tl;DR
Humans Live to teach, and so, humans live to learn, To give up on the Minority is to be a Hypocrite in the face of challenge. Even jail is/was "intended" to improve society not by locking up Criminals. But by teaching them how to Become true members of it. For the irredeemable, there is only death ):
