Dear Prof,
You never cease to amaze!
I was in dialogue with this young lady, asking her whether she was the actual girl in the pictures. In fact regardless of her answer I was about to TOFTT but then I read your detective work, flipping images, etc.
Such a shame but no surprise I guess.
One bright note is that Sabrina from aw is also currently on Vivastreet, and she's real! It just goes to show that there can be some gems on there but so hard to find.
