I am not sure, then we'll get to the point of whoring, like on YT where everyone keeps making some dumbass comments and adding "Thumbs up if you agree" at the end.
Or if there is a dislike button, respective fanboys will use that as a way to "get back" at the poster - which shouldn't effect anyone unless of course after a certain amount of dislikes it gets marked as spam ;_;
Disconnect and self destruct, one bullet a time.
