It seems strange to expect the internet to keep your privacy for you, if your PII has been leaked by you. Nobody else but you can know what you want done with your information, and people choose to post PII routinely, so it’s not possible to assume that when someone posts PII it’s actually private or an error. GPT-3 cannot be blamed for reciting things you can find in a Google search, and it doesn’t matter if the results are on page 1 or page 20. These days there usually are ways to fix leaky posts, if it is taken care of immediately, but not if you wait a few years. Either way, this doesn’t feel like clear enough thinking about what should and should not happen, nor about what society wants. I want control of my privacy, and if the internet were to scrub PII without my authorization, which seems like what you’re suggesting, that would not be control.
