You can never cover all the bases or plan for every contingency,there isnt anyone qualified to write a definitive guide to scammers because no one has experience enough and its normally learnt experience and intuition,no one can write a book on negotiating through the minefield of online dating without experiencing lots of women,and by the time you have gained the knowledge you are finally married having waded through a quagmire of unsatisfactory ladies,the scammers are constantly upgrading their ploys,coming up with new schemes,hitting it from a different angle,perhaps she wasnt interested in money but was playing a long term deception angling for the golden-ticket AKA a visa,no one knows,we are all individuals and have different things ticking away in our noggins,I had someone offer to buy me a ticket to fly to Pinas so there are genuine ladies out there
