I think these are all great ideas, and importantly more social conventions than technical solutions. The software supports this workflow right now.
When I say governance I also mean multiple servers agreeing to coordinate and communicate. Not just on blocks or mutes but also policies around scraping or engaging with third party services.
I think we should get serious about governance and minimal acceptable standards across instances. Not every instance needs to subscribe to those standards but if they do they should be held accountable to them more broadly. Users can then have a more predictable experience since they know the server has committed to and expected to uphold those standards.
Better moderation tools will only ever be a part of the solution. And if this is really the best the platform can do for accountability, the platform deserves to die and be replaced with one with better ways to mitigate harassment and abuse.
I think we can do better, but more importantly I want other people to believe it too
People have been making statements like this since 2017. The argument effectively puts the onus on those being harassed to protect themselves and not create any accountability measures against those doing the harassing.
Any solution to this problem can't put the majority of the work on the people with the least resources and support.
