Another example, beyond the two posts I shared so far on Github, involving 4 servers I spot checked:
Posting title: "Private instance (Instance cannot be seen unless logged in)"
- First server, post origin: https://lemmy.world/post/1159649
- Second server, Lemmy.ml which is home to the community, does not list it in New sort.
- Third server, listed in New: https://lemm.ee/post/807061
- Fourth server, listed in New: https://lemmy.ca/post/1237115
Noteworthy is that lemmy.world shows that @hsl@wayfarershaven.eu commented on the posting about it being off-topic. And that they are a moderator of the community. I am assuming that they removed the posting, which Lemmy.ml reflects (I did not check moderation log). So that now involves a 5th server. It also raises the question of why the moderator comment only appears on the lemmy.world server: https://lemmy.world/comment/968972
