For users themselves to decide if something doesn't contribute to the post or subverse at hand. Even if a post is downvoted heavily that doesn't mean the post goes away forever, its still on the subverse. Plus, on Voat, only a portion of voaters can downvote something seeing as how you need 100 CCP to downvote.
