@dusk the biggest downfall is that if an admin or moderator does not see the harassment/rule-breaking behavior, it won't get moderated.
There's no automated moderation based on keywords.
So if someone says the n-word towards someone else and they don't report it and nobody else sees it, it goes ignored.
This is insanity when there's millions of posts every day across Fedi and a limited number of admins that are moderating those posts.
