Had my own one of these recentley. Same as everyone else £500 bank transfer or we know where you live, very unlikey they spend all day following you around. In my case they would be waiting days to follow me home

. Whilst I know this to be an absolute outside chance of a scam. Is a little dissapointing to think of the possibility that naturally they got the number from one of girls you see. So whilst I've never had a negative experience with any of them, they are either creaming a little bit of money selling their book on when they are done or not in control of their phone.
If this were a more generally targetted campaign I think we all would have heard of this outside this community by now.
