It’s a bit weird. Only Kbin has the functionality built in to see who is giving upvotes or downvotes. The information is technically public on Lemmy too because of how federation works, there’s just no way to see it in the web UI or apps.

There’s a problem though. Downvotes don’t federate between Lemmy and Kbin, so we can only ever see downvotes from other Kbin users here. If someone on Lemmy downvotes something, I’d never even see the count change and wouldn’t be able to see who did it.

Edit: from my view, no comments in this thread have any downvotes.
