The thing with Discord, or any service, is that you really can only use it with people you trust. If it's open to the public (and yes, that includes the case of "subscribers only" since anyone can be a subscriber) then it will invariably be overrun with coomers. Perhaps some day it will be possible to spot coomers, troons, and other degenerate filth and spam-filter them decisively, but for the moment that's not possible, jannies are ineffective, and hence no chat can ever operate successfully outside of a closed, trusted group of individuals. That more or less means a group that can't grow beyond Dunbar's Number (i.e. roughly 150 tops).... beyond that, degeneracy awaits.
