Perma bans for behavior
There should be no perma bans ever for something you have put money into. Take away chat privileges and ranked play. Only leave open blind and arram, let them stew and hopefully they will calm down and earn their privileges back but never perma ban. Make a game where people can be as toxic as they want some people need to take it out somewhere stop catering to snowflakes whos feelings do not matter. When your climbing silver and get 2 games 10 mins in with afks and the team doesnt remake you suffer because there is nothing you can do, and hamstringing people to adhere to a behavior policy when they are crapped on due to something they cant control is just as wrong as being toxic.
