Melanin: worth nine times more than it's weight in gold

"Organ harvesting is a very lucrative business, it is intensified when you consider melanated organs, which cost more than organs without it. Melanin currently costs more than gold, silver, platinum, palladium rhodium and coltan combined so Haiti had value."
Even if people are selling "synthetic melanin" on the internet for ridiculous prices, and even though that clickbaity article claims much stuff about it, I still doubt that's a primary reason for the targeting of Haitian children. Seems more like a muddy-the-water tactic + racial bait...
We already know plenty about the ease of access to Haitian children due to the state of the country. And plenty of suspects, most of them involved in the earthquake relief efforts
It could be all that. I don't know. Check it though:
