It seems the Nigerian spammers have learned you can't always kill them with kindness. Now they just threaten to kill you. A woman in St. Louis received a mail that said, in part, "Am very sorry for you my friend, is a pity that this is how your life is going to end as soon as you don't comply. ... I don't have any business with you, my duty as I am mailing you now is just to KILL/ASSASINATE you and I have to do it as I have already been paid for that. Get back to me now if you are ready to pay some fees to spare your life, If you are not ready for my help, then I will carry on with my job straight-up."
