Here's a dubious reason why Nigeria is such a hotbed for 419 scams (or better known as the Nigerian Letter scam): people there are astonishingly creative with the written words! Take, for instance, the Nigerian love letter - or in this case, love SMS or text as explained by Andrew Walker of BBC News:

Your mobile phone beeps, you have received a text message.

It begins: "I swear, I will make sure I give you HIV..."

But it's not an abusive threat, it's a "romantic" text message copied from a book on sale all over Nigeria that professes to give young people the words they need to court the woman or man of their dreams.

"H is for Happiness and joy forever with an I: Incomparable love that will never V: Vanish until death do us part. I love you," the message concludes.
