Notice his comment about Africa. I would assume he is pulling this scam from so place in Africa and isn't worried about stealing bitcoin, as it isn't "legal currency"

This is obviously some "Prince of the Ivory coast" I highly doubt its possible to track him down unless all of a sudden the police/authorities had actual control in Africa (don't want to slam all of Africa here, but I do not know of a very stable country with authorities actually doing good on the whole continent). He is probably a cop at home.
Same type of person who e-mails you about western union and shipping costs upfront for your craigslist sales. Or about his family fortune that you just need to send $1000 for the transfer fees and you will get to keep the rest while his country is in turmoil.

Somehow these sites should be blacklisted by google or something. Especially when it can be seen they are scamming so much money away from people.
