I worked at a trio of adtechs. One of which anyone in the industry would absolutely recognize. There were few effective internal controls. The obstacles to lookups were 1 - all info keyed by cookie. Which users can clear, and is very difficult to get identified. That is, to look you up, I need the cookie from your machine. 1a - most devs are not allowed to run the cluster jobs to look up data. Only on the appropriate teams. 2 - but what about stapling? We required partners to pass us blind uids. Certainly nothing like emails. 3 - no data export. The business is to run ads on the customer's behalf, so there's no way built to export data except targeting lists to the exchanges.
