@Artifex @timbray Sure. Some things are spam to just about everyone, and I don't disagree that it might be useful if services spring up to provide a floor and help manage these cases.
But once things start to get even a bit gray, that's when moderating the chatter should get, well, artisanal.
Inadequate moderation is a terrible risk. But so is a world where federation just means incredible pressure to conform to a narrow intersection of every community's standards.
