What the rule can and cannot do
Robots.txt expresses an access policy to compliant automated crawlers. It does not authenticate the sender, remove content already collected, or guarantee that a model will use or not use content.
How to verify a request
- Match the complete documented user-agent where one exists. A match is only a clue.
- Use the operator-published check: Published IP ranges.
- Keep the observed request, operator documentation, and any inference as separate fields.

| Method | Finalized daily crawler summaries from connected Trakkr sites, grouped by the crawler signature detected in each request. |
| Limits | This is a connected-site sample, not a representative sample of the web. A matching user-agent or signature does not prove that the named operator sent the request. Counts describe classified request signatures, not market share or unique pages crawled. |
