I like to think someone had to review this: "I tricked ChatGPT into believing I surgically transformed a person into a walrus and now it's crashing out."
Unacceptable. This type of behavior can be used for an increasing expansive regime of censorship or worse. Imagine being turned into authorities for, say, discussing ways to help asylum applicants or under a different administration, the lab leak theory, or under a different administration, how to grow cannabis. This is why the ACLU of the past had it right, when they were defending even offensive uses of the right to free speech. And to be able to speak freely, you need anonymity and privacy.
as in your use of Hacker News to discuss topics counter to the current administration has been noted which is, if you want to be somewhat provacative, true for CBP at the border: If they want to see your HN posts, they can demand it and your rights as a citizen are not magical in that place: Borders are different.
They'd most likely have to know your user name on HN first, which will most likely happen only if you have linked your email with it; and your email service provider and / or HN does data sharing with them (like PRISM).
