WWTrade is about global trade and its terms. With respect to producers, distributors, and retailers, an assume good faith policy is recommended; it is assumed, in the absence of evidence to the contrary, that an enterprise which holds itself out as being a cooperative or engaging in trade on a fair basis, does so. Gathering information about how true such information is is on the agenda, but not at the top, as is insightful analysis of how effective the various forms action can take are.
Any contact or support of any nature for humane or fair values in trade is sufficient basis for inclusion. Think of it as you think of electricity, touching a charged object results in the transfer of that charge to you. Thus, a major company whose only contact with fairtrade is selling a few products may be included, with the provision that content regarding them and links to them focus on those products; likewise, an artist who has done art work for advertisements promoting fair trade may be included.
The exception to inclusion is products or practices which embody evil such as organic tobacco, slave labor, child labor, or organized crime, for example, due to the practices of forced abortion, infanticide, and slave labor by the North Korean government, no product made in or with an origin in North Korea may be included nor may any product or service by a company or individual which traffics in North Korean products or services.
Actually nearly all concepts and phenomena fall in this category. But to take some obvious examples, macaroni and cheese is not health food, regardless of how it is made, nor is bacon, or Ben & Jerry's ice cream. Ambiguous products or enterprises are not excluded but issues should be noted.
