I noticed that when I view this post for example on lemmy.world: https://lemmy.world/post/291005 and on dataterm.digital: https://dataterm.digital/post/54221 that both of them are the same post but with a different number of votes and comments.

I believe this also leads to different sorting of the all feed in these instances. Why is that and can it be fixed? Is it even a bug?

I even saw while having both posts open that on lemmy.world a new comment got added in realtime but not on dataterm.digital

    Federation can get messy when you start to compare instances between each other.

    • For one some instances disable down votes, so may count differently.
    • Then you might see delays in synchronisation for whatever reason.
    • Finally, federation & defederation. suppose you have instance A, B, C, and D but instance A has blocked C. Users on C comment in and upvote content on D. Instances A&B will download a copy of the stuff posted by D users, but only B will have upvotes contributed by C. Therefore, different upvotes counts.

    And that’s just what I am aware of.
