It's rare for me to see a girl on AW who hasn't been reviewed on UKP, so risks are low. On the odd occasion I have done, I always cross reference FB to punters and the girls they've seen. Only when I'm satisfied the girl is genuine would I contemplate a booking.
As I've eliminated random punting now, it's unlikely I'll see anyone 'blind' off AW. And to think when I first started this I thought AW was 'the punting bible'. How quickly things change....
