silverpill@mitra.social do you still need to if you're not using a shared inbox?

@julian It should be noted that a platform receiving a moderated conversation thread does not have to honor it for its own local users. Whether this is desired or not is another discussion.
In this case, the owner of the thread (either the forum or the person who started the thread) tells you what comments are part of the thread. Some comments may be removed due to moderator actions or user-initiated blocks.
But as a remote platform importing the thread, you may be aware of other replies that are part of the reply tree, but not in the official moderated version of the conversation according to the thread owner.
As a remote platform, you have an option. You can honor the thread owner's official version of the thread and only display the moderated version, or you can modify it. You may remove replies from actors blocked on your server, for example. But you could also add comments from the reply tree that are not part of the moderated version of the conversation. -

Just thought of something interesting. In the case of moderated threads, it may be useful to tell other platforms that you know about a particular comment, but have removed it on purpose from the official moderated version of the thread. Because there is a difference between "I didn't know about that reply due to a technical issue" and "this content was removed by a moderator."

That'd be accomplished with a
Removeactivity, most likely.For those expressing the context collection as a set of objects, then removal from the set should suffice. There are probably better signals to send.

@julian Wouldn't a remove would remove it from everywhere, including the server of the person who posted it. That may be desired, but also could lead to confusion, since on many platforms like Mastodon, they can't see threads and don't realize their comment can be deleted everywhere (including their own copy). -

scott@loves.tech not necessarily, a remove merely represents that it has been removed from a collection. A Delete would instruct the recipient servers to purge the object, and that can't be done unless the actor is same-origin.

@julian Okay, that makes sense. -

> A number of implementors follow this approach to backfill, including NodeBB, Discourse, WordPress, Frequency, Mitra, and Streams. Additional implementors like Lemmy and Piefed have expressed interest.Is this implemented currently? One weakness I have noticed in NodeBB's current federation is that posts which are in reply to a topic (e.g. a Lemmy comment) show up as individual threads until (or if) the root post of that topic shows up in the local NodeBB. It's a bit confusing of a UX, I think. Because you think:
- (Before root post) Why is this a post that seems to be just a random comment?
- (After root post) Why did that other thread disappear and why am I seeing the same comment again?

No, Lemmy does not implement either strategy, they rely on 1b12 only.
If NodeBB is receiving parts of a topic that don't resolve up to the root-level post that might be something we can fix. I'll try to take a look at it.
