relevant magazine is /m/RedditMigration here on kbin.social. You can see it's the one and only report in the modlog yet the user who removed the comment is not listed in the moderators list, is not even a kbin.social user, and did not remove a lemmy.ml comment. Yet, it was removed for me as a kbin.social user.
How is this moderation working exactly? It's understandable that lemmy.ml mods can remove things for lemmy users, and mods on a magazine can remove things on the magazine. But it seems this is an unrelated user, removing a post of a user from an unrelated instance from a unrelated magazine.
How is this possible? what's going on here?
Edit: I checked on lemmy.world's copy and the comment is still visible, meaning the removal did not federate to lemmy.world.
So I just checked on lemmy.world and the comment is not removed there like it is here on kbin. yet, kbin is the hosting instance of the community. if kbin thinks it's removed, then surely that removal should be sent out to others who look at it?
With ActivityPub there is no forced actions on other instances. When a delete happens on an instance, it sends a "this was deleted" announcement to the relevant instances it knows about. The servers that receive the message could easily ignore it and keep their copy of the message active/visible.
@Otome-chan@kbin.social oh yeah, definitely some kind of copy primacy/conflict issue for sure. I have no idea how to describe it well enough for the codeberg ticket tho - definitely worth raising.

I posted it basically asking the same question as the title and linked here. Hopefully @ernest will be able to check it out and reword it if necessary.
