Yes, the errors in capitalization are rampant to the point of humour in the scam letters I get. The errors in spelling mostly seem like someone who put all English varients together (British, American, Canadian, Australian/New Zealand, South African) and never got them sorted out again, but of course, there are also some doozies that are out and out mistakes. The style does remind me of the way I have heard Africans speak English, so I really can't fault them on that. They are probably writing the way they hear the language spoken.

I do agree with FBP that it is a sad waste, though and I had never thought about it that way before.
