While checking my spam email box, this version of the Nigerian Prince scam caught my eyes:
According to Wikipedia on the topic:
One reason why Nigeria may have been singled out is because of the comical, almost ludicrous nature of the promise of West African riches from a Nigerian Prince. According to Cormac Herley, a researcher for Microsoft, “By sending an email that repels all but the most gullible, the scammer gets the most promising marks to self-select.”[18]
To that logic – it would seem to me that the Iraqi businessman story is more plausible.
