I'd never heard of
Noka before, but a writer at the Dallas/Fort Worth site "Dallasfood.org" just did what has to be the
best commercial bullshit takedown I've ever read in which these Noka fools are exposed as con artists. I don't know if the article is true, but this person was very thorough in their research and since it's public, could very easily have their claims tested by neutral third parties. So, yeah, wow.
On a related, horrifying note, here's a web page for a guy researching
child slavery in chocolate plantations.
