Yeah, I hate Facebook, too. Used my fake account to vote.
Their most popular figure franchises are Legend of Zelda and Dark Souls, so people vote "no" if the proposed figure isn't one of those.
I've tried to explain how pointless it is (and counterproductive) to have a yes/no poll when throwing out figure ideas, they just don't get it. You can get better more accurate results by just asking people to like the post if you want the figure made, or if you're set on doing a poll, make the options "definitely yes" and "maybe if..." and encourage users to leave a comment describing what they'd like to see from that particular figure.
People tend to vote the way of the majority, and because these polls are specifically for "lesser known" characters, the majority will always be "no". This is the 28th week they've made this type of poll, and this is the 28th time the "no" votes completely overwhelm the "yes" votes.
You'd think they'd learn.
