No offense but you didn't really address my questions in any substantive way. Your answer feels a bit like spin.
Let me take another stab at the answer. 0 reputation users are challenging because our service needs to be usable for them to build up reputation without causing delays like you experienced. There are a few ways we mitigate these events now:
1. Users with low reputation are restricted from low discount rates. If you set a discount rate at or below 10%, your order is matched with a VIP earner.
2. Users who cancel orders to hedge or speculate on Bitcoin price are banned from our system altogether.
3. We improved our order tracking to get real-time updates on orders. If we detect cancellation on Amazon, we usually cancel the orders the same day.
Many of the practices above were recently implemented, and we have many more in store. We'll continue to improve our service and experience.
