The “confirmed” rates are deliberately conservative. Eldorado renders most listing detail client-side, so fields like email access are often simply not exposed — we store those as unknown, never as “no”. GameBoost publishes more structured data (exact skin counts, full email access), so where its confirmation rates come out higher, that is partly because it says more. Both marketplaces offer platform-level buyer protection, which the listing-level warranty row does not count. The LootWise Score handles this the same way: verified transferability earns a real premium, unknowns get only a mild penalty.
