Someone here at HN at least posted this link which told more of the story than I have seen anywhere else. Also search the HN archives (for now at least it seems) for interesting discussions on KF prior to these latest events.

Sorry but this feels like book burning to me.
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.
Whether it's legal or not is unimportant. My question is for the internet archive: is it ethical for them to knowingly rehost dumps of PII? Just because it's public doesn't mean it's right for them to treat it like any other page. The goal of the KF users is to harass by putting that information out there: if IA rehosts that intentionally, they're making an active choice to further the goals of KF users.
I see you've backed off from "bank account numbers" to "bank account details," perhaps after Googling the same Twitter screenshots I just found in an attempt to verify your claim. Those screenshots show a user describing a hacked bank account's balance and recent purchases. That's pretty bad; hacking into bank accounts is very illegal. The individual who broke into the account very likely committed a crime. Regardless, the screenshots don't show any credentials or account numbers. I'm not sure if posting someone's bank balance is illegal, but I'm guessing it isn't; maybe it depends on how it was obtained... don't know, not a lawyer.
Of course, the screenshot is totally unverifiable now that KF is wiped from the Internet Archives, which is the point of the submitted link.
