Australian Airbnb host used an AI-generated image of an overflowing toilet to claim AUD 1,700 in fake damages

An unidentified Australian Airbnb host tried to get 1700AUD ($1,183) from a guest by sending an AI-generated image of a blocked, overflowing toilet as 'proof' that the guest had caused damage. Reddit users flagged physical inconsistencies in the image and found it carried Google's SynthID watermark, suggesting it was made with Gemini or another Google generative AI tool. The guest later said the case was resolved and the claim was deemed ineligible for reimbursement.

What the AI did

A person used a generative AI tool to create a fake image of a blocked, overflowing toilet, which was then sent to a guest as proof of damage. The image carried Google's SynthID watermark, a hidden marker Google adds to AI-made images, suggesting it was made with Gemini or another Google AI tool, though the exact tool has not been confirmed.
