As soon as you stop being a Nazi here …

I see Bitcoin as a way to get banking to the less fortunate 99% of the world population and classifying somebody as a scammer for living on the wrong continent is what I want to question here.

So the coins are in escrow? What's your problem? How could he scam you out of these coins if they are in escrow? If you think this is to launder some stolen funds (is he buying stuff that can be turned into cash easily? gold or dollars maybe?) you may invite bitmit to check the origin of the funds for some known frauds and while this would still be racist, your trade partner wouldn't need to know about it but as I said before, these coins are at bitmit regardless of the escrow being released to your Nigger or being paid to you as the release from escrow will not happen with the exact same coins.

FYI: Nigeria has 170 million citizens. Also you might want to read about this.
