Edit: obligatory explanation (thanks mods for squaring me away)…
What you see via the UI isn’t “all that exists”. Unlike Reddit, where everything is a black box, there are a lot more eyeballs who can see “under the hood”. Any instance admin, proper or rogue, gets a ton of information that users won’t normally see. The attached example demonstrates that while users will only see upvote/downvote tallies, admins can see who actually performed those actions.
Edit: To clarify, not just YOUR instance admin gets this info. This is ANY instance admin across the Fediverse.
One of the reasons I really disliked Reddit and stopped using it years ago was this way of using the voting system. If I make a post, and it gets voted something like +4-10, and a reply that is some rewording of “that’s a dumb statement”, what am I to think? I’m certainly not going to change my mind, no one gave me a good reason to.
If one is voting because they feel they can’t stand behind their opinion if they expanded it in text… I don’t know what to tell ya.
I’m inclined to believe a lot of people do this. This is not to say they are terrible for doing this, it’s that it’s human nature. Replying to someone with a well thought out post takes effort and, from my experience, makes the me realize i don’t know shit about the subject. Point is, this way of using the voting system breeds half-thought opinions which is a host of a lot of other problems.
