Sadly, all these calls & schemes rely on there being a certain % of stupid and/or gullible people out there.

It used to the "pigeon drop" where 2 people would con an elderly person. But that meant 'personal contact'. It is much easier to sit at home and make calls and steal from you anonymously. Maybe if that crap got the death penalty......naawwwww, they'd take the odds against being caught.
