Lets say I have unlimited LLM capacity and can create any content I want in any volume.

I send it to every relay, to produce millions of replies, and replies of replies … per note, and also produce billions of notes using different pubkeys connected in nets. Basically, a super spam, but not distinguishable from a real human

And in todays nostr terms all you can do is either:

1) manually follow your friends who you know directly and talk to them only. You can even hardly include friends of friends into this scope because it will be way too difficult to handle. If you bring private relays its basically the same - manually approved and very small community

2) interact with 99.9999% of generated content which adjusts to you and, say, is all about indirectly hinting you a message like “people who are named {your name} usually die 15 years earlier and leave no legacy”

So is this nostr you want to build? Or do you believe that since today nostr content is mostly fun to you then in future for some reason spammers and other bad actors won’t abuse it by some unknown reason if it becomes popular?
