A fake order does not look fake on the label. It looks like an ordinary parcel right up to the moment it comes back as an RTO with your forward shipping, your return shipping and your packing material attached to it.
Detection is optional and billed at 1 coin per label. Cropping and sorting stay free.
Nothing extra to upload — the same label PDF you were cropping anyway is what gets checked:
You can paste Order IDs straight into your own suspicious customer list — one per line or comma separated — and every later crop matches against it. It is built from your returns, your complaints and your experience, and you can read and delete every entry in it, which is not true of a blanket rating you cannot inspect.
After a crop the workspace reports how many risky orders it found. Sellers use that number to pack those parcels last, re-check the address, record a packing video, or think twice about sending a high-value item on COD. The label still prints — you decide what happens to it.
