Funny.Great you just started the next nigerian scam.
I doubt anyone would spend the bucks to mail a scam letter to a specific name address, let alone the costs in mailing it.
Besides, if they did, you would have their address and then the Feds could get involed for mail fraud. Too risky.
The internet is a wide open area. Like the wild west, little supervision or policing and easy to get away with scams.
