@jerry I think the problem here isn't technical, it's social. In fact, I would posit that the problem *is* that everything is technically working as corrected and human beings are... well... human beings.

The tools for moderation exist, and can be used to effect (as you said), but all technical solutions have work-arounds. I mean hell, I remember when stateful firewalls were the next big thing that would secure is forever (spoiler: they did not). The issue becomes the social expectation that no one is responsible for anything, but everyone else is.

We're seeing this also in greater discourse: Who's responsibility is it to resolve economic issues? The individuals struggling to survive? The organizations struggling against each other in Elephant fights? The governments with their own failing economies?
The answer starts to coalesce at "Everyone... everyone has to do their part or this just keeps getting worse." (Consider this same concept extrapolated to Climate Change, Global wars, etc.)

I think that's where we are with the fediverse. We're seeing interactions of cultures and subcultures that are just going to happen wherever we get human beings together.

I think we're all a little bit responsible, and we all need to remember the human.

I hope that was relevant and helpful.
