Perma Chat Ban Option
I would like to give the idea of permanent chat restriction as a step before perma ban account. If you think of being toxic in chat as an addiction or disease, then always allowing the option of making comments in chat, I believe is somewhat enabling continuous behavior. As we seen from popular streams and youtube channels, while some people don't type negative things, they sure as hell say them IRL. Thus giving the reasoning, that people "reforming" is simply them finding another outlet to say their toxic thoughts and comments other than in chat. This could also be beneficial for other problems in league such as reports for things like inting, griefing, and things of a non-verbal nature. By allowing perma chat restriction, more reports of other issues can be taken into account more efficiently and timely. Popularized by high-elo streamers, the idea that RIOT cares way too much about toxicity rather than intentional feeders, greifers, and so on is the widely accepted opinion by the league community. My opinion is, that people truly do not care about toxic comments, but you as a company has placed priority on this topic, so people make reports just to because they did not like what the person said and you have given an outlet to express it. Do I care that someone who called my a racial slur or swears at me in-game? The answer is no, I do not care if that person can or cannot play the game by being potentially suspended. But you have created a culture that allows words to have meaning. You as a company to take away the chat ability, thus taking away our source of addictive behavior outlet. In the process, allowing a happier community in-game and the ability to focus on other bans that the league community find a lot more pressing then some negative comments.
