brugeman on Nostr: It doesn't much matter which relays honor what - your signatures and timestamps ...

It doesn't much matter which relays honor what - your signatures and timestamps matter. With old internet anyone could take a screenshot or save a webpage with old pricing (or even make a fake one) and start asking questions. On nostr you have signatures and structured events, so a) no fakes possible, b) much easier to prove you published newer event with newer pricing, especially if that event has comments and likes from other people.

Honestly, I'd say this is overthinking, edits/deletes exist, most relays support them, most apps support them, and bad actors will always find loopholes to ask stupid questions.
