WikiDo: Robots.txt & Crawl Policy Reference

AI Summary: WikiDo is a web crawler operated by WikiDo.com for content aggregation. Official documentation states that it respects the WikiDo User-Agent token in robots.txt. However, because the operator does not publish a static IP list or a specific reverse-DNS verification method, use standard network validation and behavioral analysis before trusting the header.

Role and policy boundary

WikiDo operates a web crawler that aggregates content. The registry records the historical User-Agent as WikiDo/1.1 (http://wikido.com; crawler@wikido.com). The official documentation confirms that the crawler respects robots.txt directives targeted at the WikiDo User-Agent token.

Because the operator does not publish a verifiable IP range or reverse-DNS procedure, this profile is marked documented-limit. The User-Agent string is easily spoofed, and an undocumented IP cannot be cryptographically authenticated. Do not assume that every request bearing this token is legitimate or that the token grants permission for AI input, model training, or data retention beyond general aggregation.

To exclude this crawler across your entire site, add the following to your robots.txt:

User-agent: WikiDo
Disallow: /

For selective access:

User-agent: WikiDo
Allow: /public/
Allow: /docs/
Disallow: /admin/
Disallow: /account/
Disallow: /private/
Disallow: /licensed/
Disallow: /api/

These are explanatory site-owner controls. Robots.txt is advisory and cannot secure private or licensed content; use authentication, authorization, signed URLs, data minimization, and origin controls.

Layered verification

Start 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, concurrency, and request rate. The official documentation does not publish a WikiDo IP range, reverse-DNS procedure, Crawl-delay, rate guidance, or verification workflow. The User-Agent is useful for triage but is not authentication.

Do not treat the word WikiDo in a header as proof of ownership. Check source IP and DNS evidence independently, and require behavioral consistency before creating a trust exception.

Compare observed behavior with an aggregation hypothesis without turning it into attribution. Public HTML, metadata, feeds, sitemaps, and ordinary assets may be requested by many tools. Private endpoints, licensed content, account routes, APIs, high concurrency, repeated retries, or unexpected bulk downloads establish impact and load risk, not WikiDo identity or downstream use.

Evaluate /robots.txt only after the actual observed token is known. Confirm that it is served by the intended host, returns a successful text response, and contains the exact group you intend to publish. An absent IP list is not evidence of robots non-compliance, but it prevents proactive allowlisting.

Page-level directives can express indexing preferences:

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

X-Robots-Tag: noindex, nofollow

These signals do not authenticate an undocumented crawler or secure private paths. Enforce sensitive boundaries in the application and at the origin. If your policy distinguishes search indexing, AI input, reference use, and model training, document each purpose separately rather than inferring permission from a registry label.

WAF and Nginx remediation examples

Because the identity cannot be cryptographically verified via published IP lists, use report-only logging and a narrow observation. Avoid broad wiki or browser rules that can affect unrelated clients:

{
  "description": "Observe unverified WikiDo candidates",
  "expression": "lower(http.user_agent) contains \"wikido\"",
  "action": "log"
}

After independent verification and a policy decision, scope enforcement to sensitive routes and preserve evidence for the rule:

map $http_user_agent $block_wikido_private {
    default 0;
    # Add only a complete, independently verified token here.
    # ~*WikiDo 1;
}

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

A User-Agent match is easy to spoof. Do not invent an IP allowlist, WikiDo ASN exception, reverse-DNS suffix, rate, training policy, or permanent trust exception. Use per-client rate limits, concurrency ceilings, timeouts, response-size controls, caching, and anomaly detection at the edge or origin. Start in report-only mode, review false positives, and restrict only after evidence supports the action.

Test public pages, feeds, sitemaps, structured data, licensed assets, account routes, APIs, 429 behavior, response-size limits, and approved integrations separately. Pair WAF controls with authentication and application authorization instead of using robots.txt as an access-control mechanism.

Review checklist

Search logs for the exact WikiDo substring and preserve the complete header, source IP, ASN, PTR result, forward lookup, path, method, response size, status, timing, rate, concurrency, and redirects. The operator does not provide a verification method.

Re-check the crawler registry, the WikiDo operator site, robots.txt, and operator contact path. Keep this profile at documented-limit until a current source publishes a source-verification method, rate guidance, or opt-out process.

Decide whether your objective is to preserve public discovery, reduce crawl load, limit extraction, protect licensed material, or prevent private access. Publish exact robots rules only after the token is known; enforce private routes with authentication and origin controls.

Review search indexing, AI input, reference use, and model-training decisions separately. The documentation does not establish downstream permission or use. Do not claim successful blocking or verification from configuration alone; validate later logs.

Record the date and reason for the documented-limit classification so future evidence can be compared. If a new deployment identifies itself differently, create a separate evidence trail.
