Indexes are unique to each instance. Post ID, Comment ID, Vote ID. There’s no way to correlate this information between two instances other than to do a full text match, post by post, comment by comment

I hope there will be a solution for this. It's so unpractical. The only sane way to link to posts on other instances seems to be to cross-post them.

If you just share a link to a specific post or comment ... people can see it, but unless they happen to have an account on that instance, they cannot interact with it. To do so, you have to search for it, and the search is not reliable.

Why can't post or comment IDs be generated hashes, and each instance uses the same algorithm?

Someone else did bring up the point that the canonical URL is stored, so that does make correlation a bit easier.

Doesn’t solve the concerns you’ve brought forth. For example, the “I don’t have an account here”. A local instance can correlate a local post to a remote post, being able to provide a “open on original instance” link but it can’t be done the opposite direction, which would relieve this problem.

As for hashing, it too certain what that would gain but at some point there was obviously a decision not to correlate by the message UUID (which would accomplish the same thing). Since I wasn’t in the room can’t say why.
