NestDaddyBot: Robots.txt & Crawl Policy Reference

AI Summary: NestDaddy’s first-party webmaster page documents NestDaddyBot as the crawler for NestDaddy Search and publishes a current page User-Agent of NestDaddyBot/2.0 (+https://nestdaddy.com/bot), robots controls, adaptive backoff claims, and webmaster contact. The registry stores an older NestDaddybot/1.0.0 (+https://nestdaddy.com/bot) string, while the live robots.txt has no dedicated NestDaddyBot group and publishes a global Crawl-delay: 1; no IP range is public. Treat the version difference and high stated crawl-rate range as verification and load-management concerns.

Role and policy boundary

NestDaddy’s official webmaster page describes NestDaddyBot as the crawler powering NestDaddy Search. It says the crawler indexes public pages, uses content scoring, duplicate detection, and spam filtering, and provides private search results for users worldwide. The page lists extracted fields such as titles, descriptions, headings, language, links, and content-quality signals. It says full HTML is processed but not permanently stored, according to the page’s stated behavior; that claim should not replace your own data-governance review or a contractual commitment.

The registry records this User-Agent:

NestDaddybot/1.0.0 (+https://nestdaddy.com/bot)

The current first-party page publishes a different version and capitalization:

NestDaddyBot/2.0 (+https://nestdaddy.com/bot)

Keep both values distinct in logs. Do not assume that the registry string is a current production header, or that the current page’s 2.0 header authenticates an observed 1.0.0 request without source verification.

The page publishes a stated crawl rate of 500-1000 requests per second with intelligent rate limiting, adaptive crawl depth up to 10 levels, daily indexing of 1-3 million pages, coverage in 50+ countries, and refresh frequency from real-time to seven days. These are operator-published specifications, not a safe capacity target for your origin. The live robots file has a global Crawl-delay: 1 and no dedicated NestDaddyBot group. For your own site, use a narrow group and origin-side rate protection rather than relying on a broad claim.

For selective access to public pages:

User-agent: NestDaddyBot
Allow: /public/
Allow: /docs/
Disallow: /admin/
Disallow: /account/
Disallow: /private/
Disallow: /api/
Crawl-delay: 5

For a complete exclusion:

User-agent: NestDaddyBot
Disallow: /

The page provides similar examples and says site owners can contact webmaster@nestdaddy.com for crawl issues, removal, verification, and technical questions. These examples are site-owner controls, not evidence that the current global robots file will match the registry version. Robots.txt is advisory and cannot protect private or licensed content; use authentication, authorization, signed URLs, and origin controls for those boundaries.

Layered verification

Begin with raw access logs and preserve the complete User-Agent, source IP, ASN, reverse-DNS result, HTTP method, requested path, response status, response size, redirect chain, timestamp, and request rate. NestDaddy’s page says its IP range is a distributed crawler network and that current ranges are available by contact; it does not publish a range or a forward-confirmed reverse-DNS procedure on the reviewed page. The User-Agent and hostname are therefore useful for triage but are not authentication.

Contact webmaster@nestdaddy.com with representative IP, UTC timestamp, requested URL, complete header, and relevant logs when verification is needed. Do not accept an address as genuine merely because it matches a range received without provenance. Record the answer and the date, and re-check it when the crawler version or network changes.

Compare observed behavior with the documented public-search role. Public HTML, metadata, links, sitemaps, and ordinary assets may be consistent with indexing. Private endpoints, account routes, high concurrency, unexpected bulk downloads, or traffic that ignores your controls may indicate spoofing, abuse, a partner integration, or another client. The page’s claim that content is processed but not permanently stored does not establish what any downstream user or separate service does with data.

Evaluate /robots.txt independently. Confirm that the response is served by the correct host, returns successful text, and contains the exact NestDaddyBot group you intend to publish. The current file contains User-agent: *, Allow: /, and Crawl-delay: 1, followed by named groups for many AI/search agents and a blocklist for aggressive scrapers; it does not list NestDaddyBot. Do not treat the global allow as a dedicated NestDaddyBot policy or as authentication.

Page-level indexing directives can express discovery preferences:

<meta name="robots" content="noindex, nofollow">

X-Robots-Tag: noindex, nofollow

These signals do not authenticate the crawler or secure private routes. Enforce sensitive boundaries in the application and at the origin. If your content has separate search, AI input, or training rights, document each purpose independently rather than inferring permission from Allow: /.

WAF and Nginx remediation examples

If logs show either registry or current-page token, start with report-only mode and correlate both versions with source evidence. Adapt the expression to your WAF provider:

{
  "description": "Observe NestDaddyBot version candidates",
  "expression": "lower(http.user_agent) contains \"nestdaddybot\"",
  "action": "log"
}

After verifying the identity and deciding to protect private routes, scope enforcement narrowly and include both known version forms only if your evidence supports it:

map $http_user_agent $block_nestdaddy_private {
    default 0;
    ~*NestDaddy[Bb]ot/(1\.0\.0|2\.0) 1;
}

server {
    location ~ ^/(admin|account|private|internal|api)/ {
        if ($block_nestdaddy_private) { return 403; }
        try_files $uri $uri/ =404;
    }
}

A User-Agent match is easy to spoof and may catch a legitimate test or integration. Do not invent an IP allowlist, reverse-DNS suffix, or permanent trust exception. The published 500-1000 requests per second claim must not override your capacity limits; enforce per-host rate limits, concurrency ceilings, timeout controls, and adaptive backoff at the origin or edge.

Test public pages, sitemaps, structured data, search results, account routes, APIs, private content, 429 behavior, response-size limits, and approved integrations separately. Pair WAF controls with authentication, rate limits, signed assets, caching, data-loss monitoring, and anomaly detection.

Review checklist

Search logs for both NestDaddybot/1.0.0 and NestDaddyBot/2.0 and preserve source IPs, ASNs, reverse-DNS results, paths, methods, response sizes, statuses, timing, concurrency, and rate. Contact the published webmaster address with evidence if you need to verify an IP or an unlisted version; no public IP range was available in the reviewed page.

Check whether your robots file has an exact NestDaddyBot group. Do not assume the live global Crawl-delay: 1 or Allow: / is a deliberate bot-specific policy. If you publish a group, test allow/disallow precedence and measure origin load; use WAF/application controls for private data.

Review whether your content policy separately permits search indexing, AI input, reference use, or model training. The NestDaddy page’s statement about processing and non-permanent storage is product-specific and does not prove downstream use for an individual request.

Re-check the official bot page, robots.txt, contact path, and IP evidence when the User-Agent version changes. Keep this profile at documented-limit because the operator policy is accessible but the registry token differs, the live robots file has no dedicated group, and IP ranges are contact-only. Do not claim successful blocking or verification from configuration alone; verify later logs and operator response.
