Permabans make no sense.
1.they cannot keep a player away from the game. 2.they punish players for spending time and/or money on the game. 3.the scaling punishment system is already punishing enough for consistent players.
All in all,the more games you play the more likely you are to get banned,the more time you have spent on the game the harsher the punishment is since your account is getting permabanned,you can create a new account after getting permabanned. The punishment system contradicts it's existance,instead of serving for punishing a minority of extremely toxic players it focuses on the widest audience of consistent players who are mildly toxic or passive aggressive.Extremely toxic/offensive players do more damage and lose little. Mildly toxic/passive aggressive consistent players do few damage and lose a lot.
