Unlike button on facebook

There is no exact "dislike button" on Facebook. Nevertheless, there is hide button concealed on the down arrow on an item to the right. If one doesn't like a specific post on Facebook then one can always hide it. On doing so, one tells Facebook that a person doesn't like the post. Since, Facebook is always looking to enhance its user experience, it always takes note on what people like and what people dislike. Moreover, hiding the post helps you focus on what one like and, allows one to stick with it.
