What was She Thinking?

I am not sure what the woman from Australia was thinking, who was mentioned in this article about her being scammed from someone she met on a dating site? Let's go over the facts:

• Her husband died 11 years ago
• She has 2 teenage kids
• She never met the guy in person
• He promised her marriage and $28 million
• She sold her home and investment property for $600,000 and sent him the money to "invest"

At the moment she is warning women to avoid dating sites because of her experience. First of all, this could have happened to her with a person she met in real life, I do not see how it is the fault of online dating. She should be warning women about not sending men they just met online, money. In her story there are huge warning flags and I think the women choose to ignore them just because she was being greedy, especially when she thought she was getting $28 million out of it. I think the real victims here are her two children, she should have been thinking about them. Now I don't think anyone deserves to be scammed, she just should have thought things through.
