How do I block ViennaTinyBot in robots.txt?
Add the following lines to your /robots.txt file: 
User-agent: ViennaTinyBot
Disallow: /
This instructs ViennaTinyBot not to crawl any path on your site. The Disallow: / directive covers the entire domain including subfolders. To only block specific sections, replace / with the path (e.g., Disallow: /blog/). Note: robots.txt is publicly readable - any bot or human can inspect it at yourdomain.com/robots.txt.
Does ViennaTinyBot respect robots.txt?
Yes - ViennaTinyBot is a well-behaved bot. It fetches and parses /robots.txt before crawling any page, following RFC 9309.
How do I verify if ViennaTinyBot is crawling my site?
Search your web server access logs for the string ViennaTinyBot (case-insensitive grep: grep -i "ViennaTinyBot" /var/log/nginx/access.log). You can also check Google Search Console → Coverage → Crawl Stats for Googlebot variants. For ViennaTinyBot specifically, filter by user-agent in your log analysis tool (GoAccess, AWStats, etc.).
What is the crawl frequency of ViennaTinyBot?
ViennaTinyBot crawls at a moderate rate. If you notice excessive traffic in your logs, you can add a Crawl-delay directive: 
User-agent: ViennaTinyBot
Crawl-delay: 10
(10 second delay between requests).
Can I block ViennaTinyBot from specific pages only?
Yes. Instead of a global Disallow: / you can restrict ViennaTinyBot to specific paths: 
User-agent: ViennaTinyBot
Disallow: /private/
Disallow: /staging/
Allow: /
This allows ViennaTinyBot everywhere except the listed paths. Path matching in robots.txt uses prefix matching - Disallow: /private/ blocks /private/page.html but NOT /public/private/.
Is ViennaTinyBot causing high server load?
If ViennaTinyBot 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 "ViennaTinyBot". 4. Use fail2ban to auto-block IPs exceeding request thresholds.
