I don't see why are you suggesting this.. Whats wrong with increasing the punishment each time? 1 hour mute, 3 hour mute, 1 day mute, 7 day mute and same thing for the bans if necessary.
I don't think that we should be thinking about comforting people who deserve perma mutes or bans. Especially if we're talking about punishing toxicity because there is what? One person that has been perma'd for it? I don't give a fuck about that 0.01% lol..
Anyways, if there was no discord, I'd take the both punishments equally to heart. I mean, I still would make a new account or continue playing on a different one, but both of these punishments would make me want to quit playing on that account.
