This submission reached third place on the front page before it was removed. I'd be interested to see whether certain user names and/or anonymized hashes of IPs always upvote atlasobscura articles. I don't understand why sites like reddit, HN, etc. hide the identities of who upvotes and downvotes things. It would be nice to be able to audit any submission or comment's vote tally at will.
