Maaaaaaaaaybe that's an interesting idea. I'd have to check out how performant lemmy API is. Also worth noting that tagging is app wide not per-account. Also since it's a vote counter, in the process it would have to clear the existing counter (or just add to your existing count) since there's nothing to cross reference.

The other/lazy option? I add an import button that takes a CSV or something and then the community just builds whatever they want haha.
