Behavior system
I think that the system have a warning system something like that. So there wouldn't be only penalty's without warning and you can warn them before they get their penalty, like a last warning. It can say something like (Summoner you need to be less toxic in games or else you will be facing a ban/chat restriction soon.) the text depends on if its a ban or restriction. And if you already thought of the idea how come it hasn't been implemented? Thank you for your time.
