Questions
Does oxfordjournals.org block GPTBot?
Yes. oxfordjournals.org’s robots.txt disallows GPTBot from the whole site (line 3: Disallow: /). GPTBot is OpenAI’s crawler for training data; blocking it doesn’t affect ChatGPT search, which uses OAI-SearchBot. Checked 9 November 2026.
Does oxfordjournals.org block ClaudeBot?
Yes. oxfordjournals.org’s robots.txt disallows ClaudeBot from the whole site (line 3: Disallow: /). ClaudeBot is Anthropic’s crawler for training data. Checked 9 November 2026.
Does oxfordjournals.org block Google-Extended?
Yes. oxfordjournals.org’s robots.txt disallows Google-Extended from the whole site (line 3: Disallow: /). Google-Extended is the token that controls whether Google may use pages for Gemini training and grounding; it doesn’t affect Google Search. Checked 9 November 2026.
Does oxfordjournals.org block PerplexityBot?
Yes. oxfordjournals.org’s robots.txt disallows PerplexityBot from the whole site (line 3: Disallow: /). PerplexityBot is the crawler that indexes pages for Perplexity’s answers. Checked 9 November 2026.
