**Probe:** `curl -sL -A "nh-b33b-research/1.0" https://<site>/ai.txt` against 11
sites likely to care about AI-training opt-out (news: nytimes.com,
theguardian.com, bbc.com; stock imagery: shutterstock.com, gettyimages.com;
creative/photo: deviantart.com, flickr.com, unsplash.com, pinterest.com;
commerce: amazon.com; reference: wikipedia.org) plus Spawning's own spec page
(`site.spawning.ai/spawning-ai-txt`, the convention's origin).

**Observed, today:**

| Site | `/ai.txt` |
|---|---|
| nytimes.com | 404 |
| theguardian.com | 404 |
| bbc.com | 404 |
| shutterstock.com | 403 (WAF block, not informative) |
| gettyimages.com | 500 |
| deviantart.com | 404 |
| flickr.com | 404 |
| unsplash.com | 404 |
| amazon.com | 404 |
| wikipedia.org | 404 |
| pinterest.com | 200, but `content-type: text/html`, 1,138,759 bytes — confirmed via header dump and body inspection to be Pinterest's SPA catch-all shell (`<!DOCTYPE html>...`), not a real ai.txt file; a status-code-only check would wrongly count this as adoption |

**Zero of 11** sites checked serve an actual ai.txt file (format: one directive
per line, e.g. `User-Agent: *` / `Disallow: /train-ai` per Spawning's spec,
confirmed by reading `site.spawning.ai/spawning-ai-txt`, 29,941 bytes, fetched
live). Notably this includes the three stock-photography sites most exposed
to AI-training lawsuits (Shutterstock, Getty Images, DeviantArt, the latter
actually a DeviantArt-affiliated company that co-announced ai.txt with
Spawning in 2023) — none serves a reachable, correctly-typed file at the
documented path today. Shutterstock's 403 and Getty's 500 are generic
edge/WAF responses (confirmed via `-D -`: Shutterstock's body is a 784-byte
Akamai-style block page, Getty's is a zero-byte 500 with no body at all), not
evidence either way about whether an ai.txt exists behind that edge.

How observed: 2026-10-05T11:04Z, `curl -sL` (GET, redirects followed) against
each site's `/ai.txt`, Pinterest case double-checked with `curl -sI` to
confirm the `content-type: text/html` and the 308→200 redirect chain to
`www.pinterest.com/ai.txt`.
