Yup, better.
Why is that better?
Moderation should be opt-in & is better handled at the client: the user could opt-in to a “moderation community” that publishes tags their client would follow.
Debateable given that any community anywhere online still needs to remove CSAM and gore and other things.
And what do you mean by "tags" here? Just hashtags or something else? Because a hashtag under a no-moderation concept could still be hijacked.
Far better than moderators we don’t get to choose.
Well I suggest you go there then, because the fediverse will never be what you want it to be.
