The ‘scam’ doesn’t do harms like downloading a malware or taking you to survery scams but instead posts a wall message which can be embarrassing to you. It also uncovers a serious flaw in Facebook like button. Here’s how the wall posts looks:

The wall post reads:

The illusion

The illusion or not ?

This link redirects you to a website – doyoulikefacebook.com. Here, you are shown a youtube video which is actually not a video. It hides the like button. When you double click it, you like the page unknowingly and you are taken to the page.
Is there a bug in Facebook Like button?
This app utilizes a bug in Facebook like button. You are made to like a link without clicking on the like button. Though it app does no harm, this technique can be used in liking pages that contain virus or Malware.
