I don't think "they" are worried about this as much as some think, they'll pressure the relays holders one way or another & they'll get what they want eventually.

that's the thing, because nostr can partition we can ultimately isolate ourselves from that bullshit but it takes a lot of extra tools, like paid relays and spam filters and all the necessary support in clients and relays to allow us to build these walls they can have their own spammy free relays, we will move to our paid relays where spam is not tolerated and expensive to do

i am already only reading and writing to relays i've paid a subscription for if i'm seeing your notes that is because the client is doing outbox model and/or my relays are aggregating other relay content related to their users

Maybe, we'll see, it isn't the first time something like that has been tried.

it's simply already happening, i am only using paid relays now, and my experience is great some people piss me off but that's life, there is no spam in my feed
