My instance has downvoting enabled, but I’ve learned that some other instances do not. Do the vote totals look different to users on different instances? It seems like some users on instances that don’t allow downvoting are unaware that it’s not the same lemmy-wide. It would be pretty confusing for them to see their vote go down.
Full disclosure, I don’t know a ton either, but my guess would be that making even more calls like that would make server load even worse
