That’s weird, I use summit and it renders like the screenshot. I don’t use connect but maybe yours needs to be updated. Only one or maybe two apps had a 10 originally before the post but it has been updated since then to reflect changes devs have made after the post.
On kbin all votes are public and you can view who down voted or upvoted someone as if it was like Facebook. I’ve seen people try to call out others for down voting something on there. Mbin is a fork and has the same functionality.
