These things are expected, they do not hurt you in any way. If a relay has deleted something that is not different from the relay never having seen that event anyway.
You shouldn't count on relays having all the events in the world, that's not what I said.
They are expected indeed. That's why one should NEVER rely on them. Don't entrust relays to moderate anything because you don't know what they are running.
Clients are always "moderating" because their choice of UI **is** moderation in itself.
That's why I also say people show NEVER use a closed-source client in Nostr. A closed-source client can create and display "events" as if they were signed by the author even if they didn't. They can create things out of thin air.
Use only open-source clients so that you can verify what's happening in code and create an expectation of behavior that can be constantly checked.
I mostly agree with you, but I think we're talking past each other.
