Report a suspicious QR

Anyone may report a PrintOnceQR link. Do not open a destination you believe is dangerous. Provide enough detail for us to identify the QR and assess the report. Reporter contact details are not shown publicly.

Copyright and intellectual-property complaints

Identify the protected work, the affected QR and destination, your authority to act, the legal basis of the complaint, and supporting evidence. We may request a signed statement or counter-notice. The operator has not represented that a U.S. DMCA Designated Agent is registered; formal registration, if pursued, is a separate legal step.
