I'm 64 and have just come back from the Philippines after meeting a lady thru Cherry Blossoms. These men you report getting scammed or killed should not be happening if they weren't so naive. There are tons of info on the net to avoid most all the hazards in meeting the bad ladies. CB has an excellent article on what to avoid.
!st everybody says never never send money period for any reason, 2nd never leave a reputable dating site like CB which you can do all your correspondence thru. That's because they keep records of all emails and scammers will be caught. A dead give away of a scammer is the want to communicate thru another non traceable form right away. Never ever make any commitment. Never ever discuss what you own. I told them I didn't own a home, nothing in the bank and only a pension. That gets rid of most the scammers. Go over and visit without a commitment and look around, don't rush. Don't meet in remote areas, just in cities in big malls for the 1st times. Never flash wealth. No need to stay in $200/night hotels. I stayed in 30 day stay clean hotels with security, AC for $300/month and maid service which I found by spending hours on the net searching for. Did all my transportation by taxi too. I did not appear as a rich although most foreigners are thought of that way.
I had a nice time with an intelligent lady that works. She never asked for money, but I did pay for all expenses together and a few inexpensive gifts like mops, coffee maker, led lights, ect. I even volunteered to have her families 800 sq ft tin roof replaced because it leaked, cost $250 with labor. I never spent more that $3000 for the whole month total. I'm going back to stay longer and investigate longer in a couple of months. These guys that get scammed would also be scammed in the states; they didn't do their homework. Art Bell was very pleased with his 1st Filipina wife till she died and has now remarried a second.
Everything in life has risk and it is up to us to learn what they are. Those men didn't. There are old guys that can't date young women in their own countries and women so poor that they want a better life. It doesn't make either one wrong or evil. If both are honest, things can work out with much satisfaction to both. Women have always looked for security in men and men in pretty young ladies for companionship that aren't into feminism but femininity.
For me it's just opening up a new door to explore. No rush. Plus they make great translators and guides.
