I think there is a simple way to deal with bans, make sure that no ban is ever permanent. I mean people go to prison too in real life, but almost no one goes forever, but on these social media platforms they seem to ban people forever which is nuts. Make it so the max ban is 1 year, and the more that a sub abuses its banhammer, the shorter the sentence is. A rule like this would make toxic subs implode all on their own.
