Nice thought, that could definitely be what’s happening. But as you say, it’s hard to detect since obviously if someone returns the item they might want to leave a bad review. But if all returns leave a good review? Now that’s suspicious. Maybe amazon should show an icon if the reviewer returned the item, and force them to explain why they returned it. But again that’s hard if they write the review before returning the item.
