Airbnb host used AI images to extort guest for repair fees, the latter successfully exposed it using a watermark detector

After a tenant checked out, the landlord claimed compensation; on closer look at the photos, the water marks on the floor were found unreasonable. Gemini detected a SynthID watermark, confirming the images were AI-generated. Airbnb determined the claim did not meet conditions and penalized the landlord. Reminder to take photos as evidence when checking out, and do not trust online images blindly.
