My guess is deleted/banned accounts, but I don’t really have a way to confirm that. Even using my admin powers, I still only see the 12 upvotes and 0 downvotes, and none of those have a vote weight different than 1.

I have been digging into the code, trying to look at where the post.score is updated, which has led me to suspect it is deleted accounts (for whatever reason). When a vote happens, the vote is recorded in a table in the database, and the post score is adjusted based on the vote weight based on the voter’s instance (in practice, this is basically always 1). However, when a user is banned/deleted, the votes recorded in the votes table are removed, but the post score is not adjusted accordingly to account for the now-deleted votes. The score just stays that number saved in the post table of the db.

@rimu@piefed.social - do you have any more insight? I was trying to think of the possibility of duplicate vote actions both contributing to the score, but I don’t think that should happen. I can’t really think of what else could make the score so out of line with the votes.
