It’s more of a cliche, I don’t think anyone actually does it, but it shows up in those cropped images of tweets people post on reddit. Downvotes should show right next to the upvotes (at least, on desktop). Is a nice feature to show both, so if it’s like, negative 1, you can see, Oh it’s actually negative 10 and positive 9, that is like 50% dislike ratio. Feels a lot better knowing its a split crowd.
edit: A word
The main post would be shared but then in the comment section you can swipe left or right to scroll through the different instances (comment section). Most comment sections don’t have such unique requirements anyways, usually on Reddit I just assume “don’t be an asshole” and on the few occasions where that is not sufficient, I get deleted and the mod notifies me of the error, then I learn. Generally people won’t familiarize themselves with the community rules before posting.
