In the official browser app, and any of the mobile apps that I have examined so far, it seems that you are only ever able to see the total number of likes, or dislikes that a post has, and you are not able to see exactly who upvoted, or downvoted the post. Does ActivityPub, or Lemmy track this information at all, or does it just keep a tally?
On kbin the votes start at 0 for both up and downvotes. If I don’t manually vote on my comment it will show me 0 votes after posting. I have no idea how it appears on other instances.
On Kbin, your comment has 0 upvotes and 0 downvotes (at the time of writing this), but when I view your comment from the original instance, it shows a score of 1.
So I guess lemmy.ml defaults comments at 1 point.
EDIT: Immediately refreshed the original instance, and I’m also at 1 point within 3 seconds of posting. So yeah, that seems to just be the default score. And upvoting my own comment didn’t change the score on lemmy.ml. But also, I upvoted your comment, and you’re still at 1 point on lemmy.ml. So I dunno if that’s a sync issue, or if “unscored” and “1 upvote” both equal “1” on the original instance.
I upvoted my previous comment and it now shows 2 upvotes for me. When I go to the original instance it only shows 1 upvote.
