Kbin doesn’t federate downvotes from other instances though, so you can only see the downvotes made through Kbin. I believe for Lemmy, the only way to see the identities of voters is through direct database access. Maybe some third party apps show that though?
I figured it was a conscious design decision. Maybe it just doesn’t work, idk. It’s kind of nice not seeing them though I am curious sometimes and will look on other instances.
