The '419 scam', or the 'Nigerian scam', named for where it originated, is one I first saw about fifteen years ago. It was obviously a scam then, and it's obviously a scam now.
It consists of an Email from a total stranger, who has enormous amounts of cash but can't get it out of their country because of whatever current political issues are in vogue at the moment. This total stranger is willing to give you a large portion of this enormous amount of cash if you help them move it into your country. Naturally, there are expenses, to be reimbursed when the cash is transferred... but of course, it never is.
Oh, come on. Surely nobody falls for this one any more? It's at least fifteen years old and it was an obvious con when it was new.
Yes, they do. Lots of them.
People are still handing over money to the fraudsters. What are such stupid people doing with money in their hands? They clearly can't be trusted with it. To quote the article:
Although the scam has been widely publicised, people still fall for it through a mixture of greed, naivety and a sense of racial superiority, the British study said.
Well, if greed and/or racial superiority are your thing, then you deserve all you get. As for naivety, there's no excuse. If you're intelligent enough to operate a computer you should have sufficient intelligence to spot such an obvious scam. If you don't, then step away from the keyboard. You're likely to hurt yourself.
As long as there are suckers, there'll be scammers. The only way to stop it is to have a form of Internet driving test, with hazard recognition classes for the seriously hard of thinking.
After all, letting these poor saps loose on the internet is like letting your dog drive your car.
That's never a good idea.
