Since there's no existing compendium, maybe a social media contest for people submitting photos of anonymized objects (e.g. in a box), books (hardback with custom cover), humans (costume/mask/etc) with Mullvad ads / billboard in the background. Crowdsource field reporting and motivate discussion about metadata in online and offline privacy.
