Quora (quora.com): AI Crawler Rules in robots.txt

GPTBot is disallowed by quora.com's robots.txt (checked ). In all, the file disallows 9 of the 17 AI bot tokens we monitor (52.9%). Observed Source · Methodology

What this means for you

robots.txt on this site disallows 9 of the 17 AI agents we monitor: 3 of 4 search and answer bots (OAI-SearchBot, Claude-SearchBot, PerplexityBot), 2 of 3 user-requested fetchers (ChatGPT-User, Claude-User) and 4 of 10 other crawlers.

An assistant that follows robots.txt may not read or cite this site when a user asks about it, because the disallowed agents are the ones that fetch pages for answers.

To publish rules like these for your own site, see How to Block GPTBot and Other AI Crawlers in robots.txt. A host or CDN can also block AI crawlers on its own, which robots.txt does not show: our hosting checker names the provider behind any domain, and our hosting price tracker shows what the plans we check cost.
