Thank you for raising your concerns. You are right that I have no desire to malign Nigerians (or the other countries referenced in the piece).
I have made a couple of modifications to the piece, including to the title. I hope those changes will satisfy at least some of your concerns. As I hope is obvious, the piece is part satire but also hopes to alert people to the scammers out there. Given the growing volume of scam emails, it appears the "scam industry" is growing.
