Facebook probably sends an HTTP request to the link to get an image preview. I doubt that any human or computer is actually "looking" at the link for 15 seconds, more likely they just messed with the concept of time on the preview agent's Javascript interpreter so they can determine the layout of the "final page" with all animations and JS completed.
