My replies via Mastodon to Lemmy posts don’t get distributed as expected. For example:
- Original post: https://lemmy.ml/post/11552444
- A reply via Lemmy: https://ttrpg.network/comment/4965852
- My reply to that: https://hachyderm.io/@otl/111887721960075860
It seems my reply only shows in these Lemmy servers:
- lemmy.ml (the server of the group to which the post was made)
- lemmy.world (the server of the post’s author)
- ttrpg.network (the server of the comment’s author)
From some other lemmy servers, my comment is not present:
- lemmy.sdf.org: https://lemmy.sdf.org/comment/8124910
- lemmy.one: https://lemmy.one/comment/6912806
- aussie.zone: https://aussie.zone/comment/6414209
I expected that my reply would show on any other Lemmy server with subscriptions to !privacy@lemmy.ml. Does that make sense? I’m hoping to help troubleshoot federation like this as I’m super excited about ActivityPub and what it means for the internet! :)
Ah ha makes sense now! The “Replying to comments” section of that article explains exactly what’s happening. If I understand correctly the community itself (!privacy@lemmy.ml in my above example) is not notified of my reply from Mastodon. If the community did know, then it would broadcast a notification of the activity to whoever else is subscribed to !privacy@lemmy.ml.
