How reviews and confirmations work

We ask contributors to share a photo they took and their own experience. Reviews go through automated checks. Flagged reviews can be assessed manually. Approval is not a guarantee that a photo is unedited or free of AI generation.

  • Email address confirmed means the link sent to that address was used. It does not prove a purchase or the identity of a person.
  • Company management confirmed relates to access to this company page. A paid plan does not verify individual reviews.
  • A review invitation does not independently prove a purchase. An order reference supplied by a company is not independent purchase verification either.
  • Publishing a photo with a review does not automatically permit reuse in marketing. A subscription does not grant that permission either.
