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! :)
While both Lemmy and Mastodon use ActivityPub, the way they send ActivityPub messages to each other differs quite a bit. There is not a simple or quick solution to this. However recently I read about Lemmy having improved integration with https://a.gup.pe/, a service that adds Groups support to Mastodon so that might be something you want to try out.
Mastodon having so many users makes it a tempting target for integration but federation with software that uses Groups properly (e.g. PeerTube, Friendica) is likely to be easier to achieve.
