I naively thought a secret list (file) with secret data is not distributed among random developers of random organizations in full but having a private access point where specific persons could be checked for no fly list by those with right for it, audited, with measures to avoid abusing the service. Potentially with training set available for developers separately. There are services where the accuracy of certain data can be validated (i.e. for cars by license plate and other data) so those who query should already possess the data of a particular person when using it and not just browse everyone in the secret list they please.
