    From the first line in the article

    Inland Revenue is giving hundreds of thousands of taxpayers’ details to social media platforms for marketing campaigns

    I’m not sure from this wording, if this means that FB et al are requesting the data for their own advertising campaigns; or the IRD are using these platforms to advertise.

    “The lists uploaded monthly are for things like student loans where the overseas-based customer population is constantly changing with people moving overseas or returning home.”

    Implies that the IRD is the one advertising. But then it goes into hashing, if the data is anonymized; how is the data used to target for example, the delinquent SL borrowers?

      Long story short, IRD are in damage control mode, saw that Facebook hashes the data, and hoped this meant they could spin it as anonymous. It’s very, very not anonymous. I did some digging, which I put in another comment chain here: https://lemmy.nz/post/14206010/10952716

      Basically, Facebook want to avoid having their customers break privacy laws for sharing data. Instead, the personal information like phone numbers, addresses, date of birth are hashed then compared against a hash of data Facebook already holds.

      The idea is you aren’t sharing personally identifiable data because facebook will only match data they already have.

      However, the whole purpose is to match up a specific taxpayer to a specific facebook user. Not even close to anonymous, even if you squint and tilt your head.
