That would be a fascinating way to do a scam. Send snail mail to people directing them to a site that looks like a major company, ask them to enter in their PII and boom, there you go. Of course now you've committed untold amounts of federal crime by using the postal system and you'd definitely get sent to federal PMITA prison if you got caught. But I could definitely see this working on older people who, bless their little hearts, just don't know any better.
