This would suggest they're running the old private gallery /cam scam. Moving the girls profile to new areas without actually moving the girls. Generating some income on the back of punters checking the private galleries to see if they are worth booking.
Mind it is interesting seeing how many geographical cock ups they make. I believe the location map is generated from the post code entered on adult work proflies. Second thoughts with the ubiquity of apps that seek location of the device used, it could be where they really are!
