Original Abstract Submitted

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for combating false advertising using crowdsourcing. In one aspect, a method includes receiving a false digital component alert indicating that a digital component presented at a client device includes false information, validating the false digital component alert based on a public key to verify digital signature included in the false digital component alert matching the public key of stored attestation tokens specifying presentation and interaction data for the digital component. In response, adding the false digital component alert to an aggregated report. Based on a false alert ratio, determining that a magnitude of validated false digital component alerts in the aggregated report meets a threshold, and triggering a false digital component mitigation response including providing a false information warning with the false digital component to one or more client devices or digital component provider.
