Cheers Jacob, sorry but I don't understand, if the page is not found how does it link to that other girl?
Not sure how it works other than when saving an image to your profile it's saved in a specific location on the AW server, if a profile is removed and pictures not deleted by user they can still be seen by using the standard IMAGE location.
So the girl in your post about https://www.adultwork.com/1316539
had that picture on her profile when it was either deleted or disabled by AW (I assume deleted). If this is the profile that had the same pictures as the new one then there is some profile swapping going on which is not, sadly, that unusual with some EE girls where Pimps control the profiles. Any good FB can then be transferred to a completely different girl.
All this doesn't mean she doesn't exist just that there are some dodgy practices at play. You wont know until you see the girl and confirm the services.
