So when one favorites a post, the post is also automatically upvoted. But sometimes I see posts with absolutely no downvotes and yet the scores are still lower than the favorite counts, which means one can remove one's upvote even after favoriting a post.
This doesn't make sense to me. Especially when the word "favorite" is generally considered a stronger form of "like". Or maybe "favorite" and "bookmark" are synonyms (I don't think so because the symbol of post favoriting is a heart and not a bookmark).
