My Opinion & A Suggestion. (you can skip to bottom for suggestion)

It is my opinion, that the people being banned, for being "toxic" in chat, could be decided more effectively, or at least more deserving. A couple of reasons, but first, what is Toxic?(not an exact definition) Poisonous, Dangerous/Harmful, Generally unsafe to be near.

1. People saying things, like calling someone stupid, or re#ar@ed, telling someone to shut up, telling someone to afk, are not "toxic" things to say.
2. People saying things like racial slurs, telling someone to kill themselves, insulting religion, or race, or ethnicity, background, country, etc. Those are "toxic" things to say to someone. Not said out of temporary anger, or frustration, but from a genuine dislike/hatred or bad attitude, to simply wanting to upset someone. 1.(B) To the point of #1, in relation to #2, the things listed under #1 and similar things, are very commonly said things, online, and irl, (yes it is immature) they do not really compare with being malicious. If you call someone stupid for making a bad play, you're not some awful person who goes around calling everyone stupid, you simply got frustrated and said they were stupid, even though you probably meant what they did was stupid. Also if calling people things listed in #1 in considered toxic 70% of games would have multiple "toxic players"

The point of the above, is to sort of put 2 categories on "toxicity" (which by the way is an incredibly insulting thing to call someone, (toxic) being that its a fairly powerful word, and when i think of toxic, i think of things like racism/antisemitism/ picking on one particular person for no actual reason other than to do it. Not general/common insults with not nearly as much impact on someone's day.) Because I don't think people should be banned for petty insults. Muted for a number of games, sure, but not banned. Even some of the people who are being particularly abusive with not much reason, could just be perma-muted.

Before my suggestion, one last string of thoughts on things that come to mind when thinking of being banned. Repeatedly Int'ing, Repeatedly afk'ing, Repeatedly griefing over not liking their auto-fill position as in giving a minimal effort or trolling instead of dodging.

The above are things that have an actual impact on a game, and whether or not you can win it, more so than mental impacts/tilting. Also if anything its these things that are more likely to make a team tilt.

My suggestion,

If not separating what is considered as intolerable chat, from petty/unnecessary comments, put toxic players into a grouping where they have to play with other players deemed toxic, until their conduct is good for a certain amount of time or games. (Although I maintain there is a difference between Rude and Toxic, especially if it is not constant, rather after playing 8-10 games and it rubbing off on you/building up.) This would leave unfavorable players with each other, and leave the positive players with each other. That would provide incentive to stop being toxic, and would reward positive players by not having anyone in their game on either team who is considered toxic currently.

Closing, somewhat relevant info/mainly a personal reason for feeling the way I do.

After being suspended on my Main Account for being "toxic" in chat, I sort of became hyper-aware of people saying rude or inappropriate, sometimes racist things in chat, mind you its only been about 3 days. I know I saw alot of it before, but now that I'm being compared to the 1% of most toxic players, I'm starting to believe maybe that's not quite appropriate, and I actually did think I was overly rude. However the 3 main things I say when being "toxic" is calling someone Re***ded, Stupid/dumb, or using curse words in an excessive fashion. I may occasionally threaten to feed or something, however usually just to get something to stop, as I don't truly intend to lose on purpose. When I started comparing my own chat behavior to other's over the last few days, I've found that in almost every game I play, there are at least 3 people being rude in chat, and in about 10%(conservatively) there's someone who says at least 1 racist slur/comment. Or tells someone to kill themselves(fairly common). In my mind, those are the people who should be suspended/chat-muted/banned, and I can't manage to compare myself to them. I've never said anything racist, I've never insulted a religion, even though I know the things I say are immature/excessive at times, I still also believe they are very commonly said things, and not truly comparable. Also it is not every single game that I'm saying something rude, when everyone is being nice and co-operative I am the same way, I try to give constructive criticism/advice instead of calling someone out and saying they're just bad. I suppose I sort of reflect what I've been surrounded by over the course of the day.

This is the reason I had the thought of a new way to punish toxic players, as I feel I can be at times rude, and sometimes I have definitely flamed or raged, but I don't think I've said anything incredibly outrageous for completely no reason, and sometimes it is over something said in the pre-lobby, which doesn't get taken into account. Also if someone who is playing with toxic players, is constantly being overly negative or abusive even compared the the toxic people they are forced to play with until whatever requirement is met, it will be very fair to say they had every chance available before being banned.

Sorry, one last thing, if nothing else, maybe implement a view-able mark system, so that people at least know where they stand, as my suspension occurred over a particular game, and since I was reported in the next game before it started, it was bumped to a perma, which was thankfully overturned since it happened so suddenly, but I also realized whether or not I deserved it, I didn't know I had been reported enough times to be approaching that state. That sort of info could be very useful.
