YouTube started with a star system, right? 1-2 stars is basically a dislike, 3 stars would be "meh", and 4-5 stars would be a like.
Then they changed it to just like/dislike, because the star rating is too granular? Either way, like with Amazon, like/dislike can have as much fraud as Google/YouTube wants. Their best partners are obviously going to have more likes to help lead to more views to help lead to more advertising.
