“Viewers should disregard the ‘Guaranteed TCQ’ label ... when the label seems to have been attached by someone other than the photographer.”
Third-party content-providers cannot credibly attach the “Guaranteed TCQ” label to an unlabeled photo; only the photographer responsible for the photo can do that (see #117).
But when publishing an already-labeled photograph, content providers can credibly reproduce the “Guaranteed TCQ” label if they also identify the photographer who is standing behind the Guarantee.
