Default-open and split policy carry different risks
A team can open search and retrieval agents while restricting the training crawler. That is not "correct for everyone" — it is a business decision about visibility, data and legal comfort.
- Evidence
- The OpenAI, Anthropic, Perplexity, Google and Common Crawl docs describe different user agents with different purposes.
- Owner action
- Build a policy table: agent, purpose, allowed, blocked, owner, review date.
- Limit of the conclusion
- A legal position cannot be derived from an SEO audit; the business owner has to confirm it.
