Identification
Its full user-agent string, exactly as it arrives at the gate:
You.com does not publish a way to verify YouBot's traffic. Treat its user agent as a claim, not proof: anyone can send it. Read You.com's documentation.
How to block YouBot
Add these two lines to the robots.txt file at the root of your site. Well-behaved crawlers read it before they crawl, so the change applies from YouBot's next visit. Nothing else on your site needs to change.
# Block YouBot from the whole site User-agent: YouBot Disallow: /
Or let it visit but keep it away from part of the site:
# Let it in, but keep it out of one room User-agent: YouBot Allow: / Disallow: /members/

Questions site owners ask
Does YouBot respect robots.txt?
We can't say yet. It has not fetched robots.txt here, and it has not touched a disallowed page either.
Will blocking YouBot hurt my search rankings?
No. YouBot isn't used by Google or Bing to rank pages. Blocking it only affects whether You.com collects your content.
How often does YouBot visit?
Here, about 0 requests a day over the last week. Visits to your site depend on its size, how often it changes, and how many links point to it.
