so lemme just tell you a personal experience and see if it makes any sense to you n maybe you can try it out sometime, a couple months back i used a client I don’t use anymore it was the one made by rabble I think, there was a feature that allowed you to create a note to only 1 relay of your choosing, i tried it out n the note was on that 1 relay for maybe 1 minute until someone on that relay decided lemme fuck with Sleepy’s test note n broadcast it, it wasn’t on 1 relay anymore which wasn’t visible to the rest of the network, now it was fully visible to most n engagement started flooding in as replies said test failed we can see the note, if that’s not amplifying idk what is. Either way I’m not technical enough to continue down this conversation 🤣 I’d love to hear from more technical people who know the process in which it works n allow them to figure out the correct terminology for it and I’ll happily listen to their points n change my mind if it makes sense to me.
