ActivityPub has an "outbox" that all software implements because it's part of the standard. It shows a paginated list of all your public posts ever. But if you scrape it "without permission" people get very upset and say you're violating their privacy. Instead we use the inbox exclusively, and only deal with events we receive. Meanwhile Nostr relays are pure outboxes. Seems like a missed opportunity. And why do they leave it in all the software if people cry and scream about invading their privacy so much?
