YSK: You can view upvote and downvote information through kbin - sh.itjust.works

If you are browsing through https://kbin.social/ [https://kbin.social/] or whatever just click on “more” then activity. There you’ll see info like boosts, reduces (downvotes), and favorites (upvotes?) Works with all instances for lemmy or kbin material

That's true, I don't think it should be allowed.

Anyone can stand up their own instance, subscribe to remote communities, and start receiving all the data necessary to show those communities. That includes posts, comments, and votes too.

Every instance operator is in control of a database containing all the activity for communities that instance's users are subscribed to. They can do whatever they like with that data. That's a consequence of how federation works.

The protocol as it stands today is also generally vulnerable to any malicious instance. A malicious Lemmy server could emit spam, send out bogus votes, or alter its users' comments after the fact (ahem, spez) and disseminate the modified versions. The main tool that other instances have to deal with a malicious instance is ... yup, defederating.
