Oh, scammers... Here how they work...

+ They contact you and try to start a friendship.
+ If they get it, they try to win your confidence fast, that's why they offer extra photos.
+ When they feel they have your trust, they start telling you about their err... "misfortunate life"
+ A few days or weeks later, she starts asking you for money.

There are men who have been scammed for thousands of dollars this way.
