There were no dumps of bank account numbers. As far as I saw, Kiwi Farms users posted only publicly-available info about thread subjects. In my opinion, certain categories of public yet personally-identifying information should be covered by US law in a way similar to HIPAA. However, that is not currently the case.
Also, info like someone's phone number and home address are only a click away once you have their full name and approximate age/geographic location, at least for people haven't taken extraordinary steps to limit discoverability on Spokeo or White Pages. People post full names and locations to Twitter all the time. They call it "unmasking" when it's someone the ruling consensus dislikes, while they know the info will be used to look up the "dox." This is not Twitter or Kiwi Farms' fault. It is the result of flaws in our legal system which allow sites like Spokeo and White pages to operate.
