But an instance is someone’s ball the server, the domain name, the admin credentials, etc. We are guests here, including community mods. And the server admins as you say are volunteers. They shouldn’t have to put up with bullshit just to please us. So any topic community like politics that generates disagreement will be precarious.

Starting a new instance isn’t the answer because of siloing and network effects. So we need more of a peer to peer model than a federation of servers. Or anyway, put the federating onto the client side. I made another post about that earlier.
