Frequently Asked Questions
Should I Block Nooshub?
No. Nooshub builds the link preview that appears when someone shares your page in a chat or social feed. Blocking it turns those shares into bare links with no title or image, which fewer people click. Its traffic normally follows sharing activity rather than a crawl schedule, so if it ever starts crawling at volume, rate limit it instead of blocking it. Almost none of the top websites we track have robots.txt rules for Nooshub right now.
Does Nooshub Follow Robots.txt Rules?
No. Nooshub is not expected to follow robots.txt rules, so a disallow rule only states your preference. Enforce the block with firewall or server rules, then confirm in Agent Analytics that its requests actually stop.
Does Nooshub Access Private Content?
It cannot. Nooshub loads only the exact URL someone shared, reads the title, description, and preview image, and leaves. It has no credentials and does not follow links to other pages.
Why Is Nooshub Visiting My Website?
Someone shared a link to your page. Nooshub fetched it once to build the preview card, and every new share can trigger another fetch, so spikes mean your content is spreading.
How Can I Tell if Nooshub Is Visiting My Website?
Agent Analytics tracks Nooshub 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 "Nooshub". Look for hits on single pages moments after someone shares a link, with no crawling afterward. Keep in mind that Nooshub 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.
