One person on /r/TheoryOfReddit already wrote about how easily people can manipulate this system: When you make a controversial post, simply block everyone who negatively responds. Then, when you make more controversial posts, you start to filter out the naysayers and your posts gain much more traction and apparent approval.
This isn't unintended, it's by design. It's a way for the majority to silence the minority. Dissenting opinions are verboten. Twitter has had a similar feature for months where you can make a tweet and restrict who can respond to it.
