yeah, the idea is that if someone is unliked by the whole group they all end up muting this asshat
and if it's something that only bugs a minority, they leave, stop subscribing to the chat of that group
the role of the relay owner (and there can be many) is to control access at the edge of that process, so, in theory, you can have like 2 relays joined and many overlapping clients passing messages back and forth between users connected to each side
but it could happen that on one relay, you have faction A, and another relay, faction B and they can thus peacefully decide to be separated if the relay owner is good about this and realises that it's best for everyone to let the cult drones have their #hashtag on one side and the rest of us on the other, you see what i mean?
this is a dynamic process and this is why ... and it makes me sad that i have to harp on about this but really, the modern kids have been brainwashed by modern social apps to have this belief that moderation is some magic wand that just happens and they don't realise it's done for the benefit of advertisers and spook agencies involved in mass manipulation campaigns
