User accounts are fragmented and just because you signed on at lemmy.world doesn’t mean your account exists on lemmy.ca.

Communities are fragmented and /c/games on lemmy.world is completely different than the one on lemmy.ml with its own users, set of posts, etc.
Lemmy does not currently allow for instance or user migration.
https://github.com/LemmyNet/lemmy/issues/3057
Nor does it allow for shared communities (ie the aforementioned /c/games is unified across multiple instances)

We are in the early days. If you’re eager feel free to join in the development on these any many other core issues. There’s real potential here.
I swear upvote counts are isolated to individual instances too. I don’t think they are supposed to be… But one post on Lemmy.world viewed from Lemmy.world shows hundreds of upvotes, but on another smaller instance it shows 5 upvotes.
I hope that’s not the way Lemmy is intended to work.
It makes no sense at all
This can happen if federation breaks for a while, I think. For instance, if a lemmy instance goes down and can’t receive activity for a time, I don’t think there’s any mechanism to backfill that activity
I feel like the Reddit migration is really putting the protocol to the test. There’s no load balancing so if your instance goes down you’re kinda screwed
An individual instance can be load balanced pretty easily, but that’s on the admin of that instance to implement.
