@Finn dAbuzz,
And those who do, end up on sucker lists, which are sold and are big money. This is why we see such egregiously bad spam. It's to keep the bar as low as possible, 'cause a person who falls for that will fall for anything.
Sadly, their targets are generally the elderly or undiagnosed mentally ill who don't have caregivers or family or coworkers or neighbors to bounce anything off.
