The first is I feel that if an account has been banned for say 6 months to a year, that the player should be given their chance to prove they reform and if they get any type of punishment for toxic behavior after getting the account back, the account should be permanently banned again and not given a chance to prove itself.
Why should Rito do this? What value will this bring to the player base as a whole to bring back toxic perma-banned players?
The second is that instead of permanently banning players, test out permanently muting them, this way they cannot type at all except for the pre game lobby and private messages.
It's been done already. It results in people resort to other form of game play offenses to be toxic since they can no longer chat. This will result in worse experience for the player base as a whole.
it is very easy to get another account or level one yourself and just be toxic again.
This game is free-to-play, free to create new accounts. That easy part is very much true. However, not that many people after losing all their progression, champions, skins, ranks, etc. to permanent ban would be so willingly create new accounts to play again. It is far more acceptable to deal with the few who do create new accounts and be toxic again than give toxic people 100% chance to continue to be toxic via game play offenses with their main accounts.
While if you permanently mute someone, they cannot flame at all and then account selling will also cease to exist since people won't need to buy accounts anymore if they don't get permanently banned.
You are reaching. Buying account runs the risk of being perma-banned out of the blue whenever Rito decides to do a ban wave of botted accounts. Perma mute is hardly a punishment for some people. They don't need to chat in order to troll. You are effectively advocating for people to freely be toxic without consequences of any significant.
I hope someone sees this message and takes it into consideration.
Your suggestions had been suggested to death every other weeks on here for probably years. Rito already considered and tried it already. They did the unbanning experiments TWICE, once with terrible result and second one we speculated to not end very well either. Rito already did what is basically perma chat restriction. People resorted to game play offenses to get their teammate's attentions and created even more toxic environment for the player base. I advice you to abandon your hope here and now and save the heartache of being ignored.
