Thursday’s most-read item on Hacker News was “How to Write with an LLM,” a craft essay on sockpuppet.org that drew several hundred points and a comment thread running well past two hundred replies. Most of the argument was about taste: whether model-assisted prose sounds like a person, whether the sentences earn their keep. The thread’s favorite objection was the aesthetic one — if you can’t be bothered to write it, why should anyone read it?

Fine. But while the commentariat debates prosody, the docket has moved past it. On Sept. 15, Law Commentary reported that a Los Angeles Superior Court judge, Elizabeth L. Bradley, fined a State Farm lawyer $999.99 over seven fabricated case citations. In March, a Sixth Circuit panel sanctioned two attorneys whose briefs carried more than two dozen invented citations and misstated facts, ordering each to pay $15,000 to the court registry, cover the other side’s full appellate fees across three appeals, pay double costs, and report themselves to the bar — that per a client note circulated by a Chicago business-law firm. In June, a federal judge in Mississippi canceled a trial outright after both sides filed fabricated citations and suspended both lead attorneys from practicing in that district for two years. Researchers had documented 1,598 court proceedings involving AI-generated content as of June 9.

Notice what’s actually being punished in every one of those cases. Not bad writing.

The Thing Being Enforced Is Not Authorship

The signature.

Every serious document in professional life carries a personal warranty bolted to the bottom of it: the attorney’s name, the auditor’s attestation, the officer’s certification under securities law, the notary’s stamp. That warranty was designed in a world where the signer and the typist were the same person. It was never really a claim about who composed the sentences — the associate wrote the brief, the partner signed it, and the fiction held because the partner was presumed to have read the thing and could be professionally ruined for not having done so.

What AI degrades is not prose. It unbundles composition from accountability while leaving the accountability in place. The signature still carries full legal weight. The typing no longer corresponds to anything. That is how you get the Mississippi case: two sides, both faking it, a trial date blown up — not because the writing was poor, but because nobody could say who had done the work, which is the only question a signature has ever answered.

This is the part the writing-guide genre, however well-intentioned, cannot reach. A style manual can teach you to make model output sound like you. It cannot make you the person the document says you are.

A $999.99 Fine Is Not a Deterrent

Look at the numbers, which are the most revealing thing here. Fifteen thousand dollars to the registry, per attorney, for two dozen fabricated citations across multiple appeals. Ten thousand dollars from a California appellate court for briefs “replete with fabricated legal authority,” plus a state bar referral and a published opinion. And in Los Angeles, $999.99 — a figure so oddly precise it reads as a judge’s joke.

Set that against the economics. Verifying every citation in a long brief takes an associate hours. Faking it takes a prompt. The expected value of cheating stays positive for anyone who expects to be caught only occasionally, and the sanction, when it lands, is a nuisance rather than a catastrophe. Courts have rediscovered what every enforcement regime discovers eventually: a penalty is only as strong as the probability of detection, and detection here depends on opposing counsel bothering to check — which, at roughly a thousand dollars per exposure, is not obviously the rational move either.

I asked where the money actually sits. “We stopped underwriting the brief and started underwriting the process,” an underwriter at a professional-liability carrier told me, on the exhibit floor at a renewal conference in Chicago, next to a booth handing out stress balls. “If the firm can’t show me how a document was verified, I don’t care how good it reads.”

The Rules Are Being Written by Carriers Now

Which brings us to the genuinely awkward part. The institutions that could settle this — bar associations, courts, licensing boards — are moving at the speed of published opinions, one five-figure sanction at a time. The institutions that will move faster are insurers and general counsel, because they price risk instead of adjudicating it.

A firm whose malpractice premium depends on a documented verification workflow will adopt one this quarter. A firm waiting for a bar rule will adopt one eventually. The result is a private governance regime over how professional writing gets produced: audit trails, attestation logs, human-review flags baked into document management software. Nobody will have voted on any of it. It will not look like regulation. It will be a line item in a renewal letter.

That is a strange place for people who reflexively distrust mandates to end up — not opposing the rules, merely discovering that the alternative to public rules is private ones with worse visibility and no appeal. The disclosure fix everyone keeps reaching for, a footnote reading “AI-assisted,” is worse than nothing. It converts the signature into a shrug. What a court needs is not to know that a model helped. It needs to know which human loses a license if the citation is fake.

So by all means, read the sockpuppet essay. It is a good piece about sentences. Just don’t mistake it for the story. The craft debate is happening on the front page. The accountability debate is happening on the docket, in fee awards and canceled trial dates and premium renewals — and it will settle what AI-assisted professional writing is permitted to be long before anyone finishes arguing about the em-dashes.
