Its for me, trying to see who's been looking around my fb.
There's no Facebook built-in method; however, you can do a simple hack to find out.step 1. Google search an image of a woman with a 6 pack
step 2. Visit blasze.com, paste the link of the image you found and the website will provide you a link to use instead of the original link
step 3. obfuscate the link using Google shortner goo.gl (it looks innocent enough right?)
step 4. post the new goo.gl link on your Facebook profile with a caption that you're sure will get someone to click; like "New Years Resolution = Sexy 6 Pack"
step 5. Wait. You'll get identifying information of the person that clicks on the link and they won't be none the wiser because the image of the girl with a 6 pack is all they will see.
bonus step: instead of a random image, use a website that you have access and can embed a website referrer. As you receive visits using the above method, you'll have the exact profile and identifying information of who visited your website.
