@scott The way "post moving" gets handled is probably with a Move activity, which is both delivered to the author(s) of moved posts, as well as quite possibly added to the conversation collection in some systems. For example, Discourse will show users in the middle of a thread that "moderator moved 6 posts to other topic". This means that even if the post author never understood the Move, anyone "following their nose" has a way to get to the "new" conversational context.
