Hey cyberdemon93,

I've actually see that same image floating around. From the best of my understanding it works like this: everyone on Facebook has an ID number in their database. These numbers are really, really long - but from the best I can figure out when you type the numbers in that code you are matching a user whose ID number contains the numbers "618" in that sequence.

When Facebook sees that, it looks up the user and substitutes in their name in places of the code.

Of course, don't actually work for Facebook, but that's the best I can figure out. :)
