I agree with the points/concerns stated above. A Safe Seller List is a good basic concept. So, I want to keep it simple! The way I see it, ALL the Primary sources
would be the well-established, long time familiar names. They are respected, have met the test of time, and can be trusted to serve the
interests of our growing fig community. They are on the Primary List because they are experts with deep roots and a reputation to maintain. We all know who they are!
The Secondary Sources would be everyone else who is currently available to sell. Anyone, even novices can be added the the secondary list.
It will then be up to the buyer to do their own research on the posts, comments, past transactions, etc. before choosing a contact.
No guarantees, so the buyer will need to take the initiative and become an informed consumer! I wouldn't select someone just because they're on the Safe Sellers List.
As they say, Buyer Beware.
