My experience is that discords that arent properly moderated go through a boom/bust cycle.
And that whether in the ascendency or the fall, the moderators trying to maintain complete opaque control will fight to the death to keep it that way.
And where moderation is done more by feel than by rules people start self censoring and then disengage entirely.
But then you go to a discord that has moderation figured out, and its just... a nice place to be?
