Probably everyone knows what 419 scam is. Usually such an email is sent to your email address, claiming that you could a good percentage of an illegal transaction as long as you provide some advanced fee and bank account information.
Yesterday, I got a real postal letter from UK. Someone named “Charles Wilson” of “Capital Management and Investment Ltd, UK”, claimed that I could get a share of $15.5M if I help him transfer to money out of UK. Of course, I know he will be asking for my bank account information. Unlike scammer emails which do not cost anything, I see a real postal stamp of 69 pennies on the envelope.
Time is hard for 419 scammers. It needs some (small) upfront investment to be a good 419 scammer nowadays.
