Expected Behavior
MoonSpider crawls websites to build AI training datasets, and its operator decides which sites, how often, and how deep it goes. Expect broad sweeps that fetch far more pages per visit than a search crawler would, on an unpredictable schedule. Volume can run heavy while a collection pass is underway, then stop entirely.
How To Block MoonSpider With Robots.txt
Add this rule to your robots.txt file to block MoonSpider from accessing your entire website, or use Automatic Robots.txt to block all AI data scrapers at once. You can customize which pages are blocked by swapping out / for a different path.

Frequently Asked Questions
Should I Block MoonSpider?
Block it if you want control over how your work trains AI models. MoonSpider downloads your content into training datasets without attribution, compensation, or any promise of traffic back. The case for allowing it is reach, because models trained on your content can surface your brand in AI answers. Neither choice changes your Google rankings. Almost none of the top websites we track have robots.txt rules for MoonSpider right now.
Does MoonSpider Respect Robots.txt?
Yes. MoonSpider is expected to honor robots.txt rules, so a disallow rule is the right first move. Automatic Robots.txt adds and maintains that rule for you, and Agent Analytics confirms MoonSpider actually honors it.
Does MoonSpider Access Private Content?
MoonSpider targets public content, but the boundary is not always respected. Some training data scrapers go after paywalled or gated pages when the operator wants that data. If a page loads without signing in, assume it can be collected.
Why Is MoonSpider Visiting My Website?
Your content matched what Moonshot AI wants in a training dataset. MoonSpider discovers pages mechanically, through links from other sites, sitemaps, and seed lists, not because anyone chose your site personally.
How Can I Tell if MoonSpider Is Visiting My Website?
Agent Analytics tracks MoonSpider visits in real time alongside every other known AI agent, crawler, and scraper. You can also check your server logs for requests whose user agent string contains "MoonSpider". Look for broad sweeps that fetch large numbers of pages in sequence. Keep in mind that MoonSpider doesn't publish a verification method, so any client can claim its user agent string and a log match is a hint rather than proof.
