I'm just getting familiar with lemmy fediverse and trying to make my way through it after getting out from reddit. I'm trying out liftoff app for android and I'm seeing way more double posts from different instances from same users. Same content from same users on multiple instances. I thought fediverse supposed to, You post in whatever instance you are and it'll be shared among all instances. I'm more confused now.

Might not be what you mean but, it seems to me the sharing among instances have significant delays.

That increases risk of users posting the same thing from different instances.

Crossposting is of course as much a thing as it was on reddit. If for instance both lemmy.world and lemmy.ml has a technology community, they are 2 separate communities, with each their moderators.

You can also subscribe to both separately.

You can post and comment to communities disregarding which lemmy server instance you are on, as long as they are federated.
