Should paid relays accept zap receipts, if the pubkey that signed the contained zap request is on the allowlist to post? I think it would make sense.
I'm asking, because my Lightning account just received a zap with not a single relay in the list that it could post a receipt to:
["relays", "wss://nostr.wine/", "wss://theforest.nostr1.com/", "wss://filter.nostr.wine/?broadcast=true", "wss://purplepag.es/"]
There is no way to control user devices and the software they run for any of our open protocols, so there's simply no way for server providers to scan E2EE content transmitted via their services.
Let them cripple WhatsApp and Signal. Why do you care so much?
