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.
And just think how much data you can gather by sending out puppet accounts on various instances, accounts that will serve only to publicly state an opinion, such as “I support this candidate”, so the data on the people who upvote it can be harvested and categorized more easily. There is so much data harvesting potential here with a little imagination, and with a little more, a lot of ways to use that data to influence the way average users engage with the fediverse.
That site would also be a great advertisement for Lemmy. Come here to our decentralized platform, where you can vote…but you better not, lest you end up on the site. What social network wouldn’t grow when users are peer pressured into not using one of it’s basic underlying mechanics that makes the whole thing work?
