I think having the option to post to multiple relays, and using paid relays to ensure aligned incentives is probably good enough for most, and doesn't required extra knowledge

But yeah, if you want the most certainty and sovereignty, there ia no way around doing it yourself unfortunately

Then stop supporting liars and make it so more of the advertising comes from people like me

I don't lie when I advertise nostr, I just say stuff like "nostr has never banned a user" which is exactly as straightforward as I say
