Well, let’s see if this is for real. If you click on the link or image on the status update as seen on the screenshot above, you will be redirected to apps.facebook.com/dislike-plugin, The Dislike Button application page.
If you hit the “Click Here” button, the app will request your permission to post status updates on your wall. But before you grant the request, the app had already published an update to your wall.
Now, once you granted the request by clicking “Allow”, you will be asked to complete an offer (a survey perhaps) before using what is said to be a great Dislike Button feature.

I smell something silly here, to be honest. Don’t be tricked! Sorry, The Dislike Button you wish coming to Facebook doesn’t actually exists, at least for now. And Facebook don’t have such feature yet; even no official announcement if they will implement such.
