Today online dating is everywhere, and for many people it works!
For untold others, it's just another way for scammers to prey on lonely hearts for cash.
It will all feel so right, and end so horribly wrong.
The VAST majority of these scammers are located in former Soviet states like the Ukraine, or in Western Africa (think Ghana, Benin and Nigeria) but usually pretend to be located somewhere else, even in the USA.
It's rare to get a phone number, and if you do, they frequently restrict it to text messages only, or VERY brief phone calls.
