How do I block Factset_spyderbot in robots.txt?

User-agent: Factset_spyderbot
Disallow: /
This instructs Factset_spyderbot not to crawl any path on your site. The Disallow: / directive covers the entire domain including subfolders.

Does Factset_spyderbot respect robots.txt?
⚠️ Factset_spyderbot may not always respect robots.txt. For guaranteed blocking, combine robots.txt with server-level rules (Nginx if/return 403, Apache SetEnvIf, or Cloudflare WAF).
How do I verify if Factset_spyderbot is crawling my site?
Search your web server access logs for the string Factset_spyderbot (case-insensitive grep: grep -i "Factset_spyderbot" /var/log/nginx/access.log).

User-agent: Factset_spyderbot
Disallow: /private/
Disallow: /staging/
Allow: /
This allows Factset_spyderbot everywhere except the listed paths. Path matching in robots.txt uses prefix matching - Disallow: /private/ blocks /private/page.html but NOT /public/private/.
Is Factset_spyderbot causing high server load?
If Factset_spyderbot is generating excessive requests, you can: 1. Add Crawl-delay: 30 below the User-agent directive in robots.txt. 2. Rate-limit the user-agent via Nginx's limit_req_zone or Apache's mod_ratelimit. 3. Block it outright at Cloudflare WAF with rule: http.user_agent contains "Factset_spyderbot". 4. Use fail2ban to auto-block IPs exceeding request thresholds.
