I’ll have to think about the first two points, thank you. I don’t have a good idea how to answer those at this point in my journey here.

On the third- sorry if I was unclear, yours is obviously a lot simpler and easier to implement on the tech side. And having the network saying the profile is dead is good. But doesn’t provide much assistance for recovery of original social graph and wouldn’t it require people to associate their nostr identity outside of the network? I was thinking under the conditions that someone might not have that. I guess yours requires people to be social which is not a bad thing. When I said scalable should probably have used a different word there.

I really would like to find a way to recover the social graph, at least effectively, but maybe this is an intractable problem?

I also don’t understand what you mean by “server” in this context, but that’s a me problem, not a you problem.
