Nobody pays KFA for its Django code. Sellers pay 6.5% + $1 to reach buyers without eating scam risk, and buyers pay 6.5% for a used board that a human has opened, inspected, and PCB-tested before it ships. The free alternative is r/mechmarket, where trust is flair count and PayPal disputes; the fee is the cost of turning that into a guarantee.
