Maybe I remember the Grok ones more clearly but it felt like “I asked Grok” was more prevalent than the others.
I feel like the HN guidelines could take inspiration from how Oxide uses LLMs. (https://rfd.shared.oxide.computer/rfd/0576). Specifically the part where using LLMs to write comments violates the implicit social contract that the writer should put more care and effort and time into it than the reader. The reader reads it because they assume this is something a person has put more time into than they need to. LLMs break that social contract.
Of course, if it’s banned maybe people just stop admitting it.
