Do you think this moderation paradox - of needing curation at scale, but automatic moderation + "user flag" moderation being inadequate - is a universal problem

Do you think this moderation paradox - of needing curation at scale, but automatic moderation + "user flag" moderation being inadequate - is a universal problem, or do you think it's specific to ad-funded platforms? I wonder if a patron-driven community that sets its own moderation policy wouldn't have this problem, because when a topic gets too large it will inevitably splinter into smaller communities where the preferred moderation style of each subset can be catered to.
