Keep in mind, it’s not a real score. That’s only what that user sees, based on upvotes from servers their instance is federated with. My instance is federated with a different list of servers, so my score for you is slightly different at 25584. Somebody on a third mbin instance will likely see a similar, but still different score.
I can’t see any posts from the last year when viewing that from Mbin. Which is weird because I’m also somehow already subscribed to it, so I should be seeing newer posts.
