Open the more menu on any listing and choose Report. Pick a reason (scam, prohibited item, wrong category and so on) and we review it within hours. Reports are anonymous: the seller never sees who flagged them. For urgent safety concerns, email safety@jinu.app.

Common red flags: a price far below market, a seller who refuses to meet in person or on a video call, a request for payment by gift card, wire or crypto, or a story that does not match the listing. When in doubt, walk away. There is always another listing.

• Meet in a public place during daytime.
• Inspect the item before paying.
• Use cash or a verifiable in-person payment app.
• Never share account passwords or one-time codes.

File a police report locally first: that is the most important step for any chance of recovery. Then send us the report number plus the scammer's handle and the message thread at safety@jinu.app. We ban the account and cooperate with law enforcement requests.
