No DisLike Facebook button, only UnLike button
There is NO dislike button on Facebook. Anyone spreading information about official dislike Facebook button has bad intention to grab your Facebook information or harm your computer. Most likely, Facebook will never have dislike button feature – as it does not make sense. If introduced, most users will use it to mark down other user’s content. As of now, you can ONLY like specific content on Facebook and further use unlike Facebook button to unlike previously liked posts or pages on Facebook.
