At the time that I had joined this instance, I believe none of the posts from !30rock@dubvee.org were viewable on this instance. When I subscribed to the community, most posts then became available, but few-to-none of the comments/votes did. Everything since subscribing is entirely in sync. Check it out yourself; when sorting by Old, you see many posts from well before I had joined this instance, but they do not have comments and have just the OP's initial one upvote:

I have noticed similar behaviour with other communities, so I don't think "actions" are just stuck in the "queue" or whatever. Is there anything I can do to get my instance fully in sync with a particular community? Or could this only be remedied by an administrator of one (or both) of the instances?
Great information, I appreciate it!
Considering this is just a silly community about a TV show that ended a decade ago, I absolutely agree. But, hypothetically speaking, could it be possible to fully sync, votes and all? Given some important community where vote counts actually did matter for some reason, could admins from both instances coordinate with each other to manually query their respective databases to get historical posts, comments, upvotes, and downvotes synchronized?
Hypothetically, sure: the info exists in one place - they'd just have to arrange a way to transfer it.
Votes themselves are a simple activity, but each one can cause a surprising increase in storage requirements (every vote has a user, every user has an instance, every instance has admins, and all these entities might have avatar and banner images associated with them). Most instances are run by one person as a hobby, and paying for DB and image storage seems to be the no. 1 reason for instances folding, so there's generally a question of how much one instance should be an exact mirror of another one.
