In a typical bid entry there are between 500 and 5000 bits of information relating to an individual, per the definition of GDPR. And that's not including the dreaded "IFA", which uniquely identifies the individual.
I don't agree with your claim that "the geodata is often fraudulent".
Anyone can read the linked pdf specification (above), download sample data from the exchanges, and judge for themselves.
Also, most of the data on it is pretty shitty with lots of fraud since the publishers want to get more money. The geo data is often fraudulent (https://en.wikipedia.org/wiki/Geographic_center_of_the_conti...), and that's why companies that bid hire data scientists to sift through the fraud.
There's also rarely, in my experience, year-of-birth or any personally identifiable data.
