Again,add only Bitcoin experts to the Trust Networks.
Knowledge does not necessarily have to do anything with trust. I don't see the system properly functioning in that way, nor do I see 'Bitcoin experts' wasting their time with trust ratings.
Because we have passed the authority to noobs who don't understand what are they doing and why they're doing it.If a seller wants to get rid of Giftcards let them be,they have buyers to purchase who really don't care how it comes from.Why a third party has to interfere without being asked to ?
I know Bitcoin experts won't be interested in such a ambiguous system.The point was, add people with Brains to the Network .
