Like in reddit If a post generates more than x votes its hidden? I know it's similar to the "inappropriate" button but most people will agree that not liking or agreeing to someone doesnt mean they think the post is inappropriate. However with a downvote you can get a good representation of what the forum members feel about a particular post/ or poster. Which might encourage them to change their style of writing. That can only be a good thing right? You'd naturally assume if there are 10 likes to a post then its a good post. But it there were 10 likes but 10 downvotes you'll know its a controversial post. 10 down votes and zero likes basically means its trash and no one agrees with the poster.
