Okay, I'll show you kiddies this once more, since you're too ignorant to grasp this the first hundred times I showed you:
Each facebook account is assigned a numerical ID. This ID, which used to be displayed on a persons profile URL (now changed by whatever name they have chosen for themselves) can also be found in every link that traces back to that original facebook account.
I will use mine for example.
Because of the now changed name-in-the-URL thing, you must click on someone's photo albums to display their user ID in the URL. Note mine in this link: http://www.facebook.com/corbin.chris...3&id=588437643
See that last part? id=588437643? That would be my user ID. Now, all you have to do is figure out WHERE that ID appears in a picture URL, so you can extract it, place it in another URL that will link you directly to someone's profile.
As you can see in that link, my ID shows up as the 3rd cluster of numbers in. Therefore, we go to the original link of the person we are trying to stalk, and find the 3rd string of numbers: 774258427. That would be "mystery girl"s ID right there.
Now we just go to our address bar, and enter in the ID into the generic Facebook profile URL: http://www.facebook.com/profile.php?id=774258427
Wallah. Mystery girl found.
