This news made me laugh and if its true that a good start

normally we used to see things the other way around,people from Nigeria scamming people with Emails and other scams and now they got their arse kicked by some smart arse girls

Maybe it's a fake? Where in Nigeria billionaires? This is a poor country where people are dying from hunger and disease. I too have faced many times with the Nigerian scammers. True, they deceive primitive. Probably not enough education.
I'm sure there is a small percentage of Nigerians that have money. Someone has to own all the land with the oil wells. Its probably this guy.
