I do vaguely remember being able to see the number of downvotes a comment got tho

It was so wild. Some users figured out that you could make a title or comment entirely blank if you added an emoji to it. It drove the admins nuts. They started changing the titles themself haha XD! Ah man were those the best FS times...

So that's how they did it...
