Interesting idea! I like it. I suspect we'd still end up wanting to maintain some kind of allowlist, since it would be misleading to see many other existing HTTP headers...

Yes! Obviously there's precedent in various places, including Mastodon's export/import, and further afield WordPress's archive format and [Blog Archive Format](https://indieweb.org/blog_archive_format). How do you see this relating to the standard though?...

Oof yeah, let's merge these instead of duplicating. Also @Timothyjchambers did a bit of research on this recently too, specifically on what's deployed in the wild, he might want to...

Hmm! I don't entirely follow. Could you post a specific example of where you see these end user ids? AP does specify both [`likes`](https://www.w3.org/TR/activitypub/#likes) and [`liked`](https://www.w3.org/TR/activitypub/#liked) collections that expose each...

> This is by spec reading rather than protocol inspection; so I don't have server-server messages to hand. I highly recommend looking at those! Relatively easy to do with curl,...

> Oh! What does Mastodon do if it receives a AP like to a post it made; and I assume it will send a 'like' if someone hits the *...

@nightpool I expect you're right about the spec itself, but it is worth noting the fediverse's broad deviation from this in the wild with [authenticated fetch aka secure mode](https://docs.joinmastodon.org/spec/activitypub/#secure-mode). Not...

@nightpool True! I was thinking of AP itself specifically. If you're an AP server implementing S2S, in practice right now you can't consistently fetch objects/activities across the fediverse without auth,...

Thanks Evan! Another interesting conclusion this morning: "accessible to all users, without authentication" seems to be independent of fetch mechanism, ie it applies to both human users viewing HTML posts...

@TallTed true! Reusing server domains and actor ids over time is a fascinating question more broadly. I wonder if anyone has ever thought it through or written anything up. Best...
