This is a great point because in the Lemmy UI, this information isn’t shown, and you can’t even list out all posts you’ve upvoted. As most of us coming from Reddit, we’re used to upvotes being private, and probably assume it’s the same. I understand the technical reasons for having the information public, but it is not clear from a user perspective that it’s public.
Don’t NFTs have more protections? If I sell you an NFT, I can’t unilaterally revoke it.
