Do's and Dont's when you
encounter the 80legs web crawler

What is voltron?

If you've come to this page, then you're probably interested in learning more about our web crawler, identified as user-agent "voltron."

Voltron runs on a grid computing platform that consists of several thousand computers, which is why you may see our web crawler access your site from many different IP addresses.

Why is voltron crawling my website?

Voltron is the user-agent used by 80legs, a web crawling service provider. 80legs allows its users to design and run custom web crawls. So, if voltron is crawling your website, it means that one or more 80legs users created a web crawl that went (eventually) to your website.

People use 80legs for a variety of reasons, including providing data to their own search engines, monitoring trends in online opinions, and for other interesting applications.

Help us crawl your website properly

If you feel that voltron is crawling your website too quickly, please let us know what an appropriate crawl rate is for you. If you'd like us to stop crawling your website, the best thing to do is to block our web crawler using the robots.txt specification. To do this, add the following to your robots.txt:

   User-agent: voltron
   Disallow: /	

If you block voltron using robots.txt, you will see crawl requests die down gradually, rather than immediately. This happens because of our distributed architecture. Our computers only periodically receive robots.txt information for domains they are crawling.

Blocking us by IP address

Blocking our web crawler by IP address will not work. Due to the distributed nature of our infrastructure, we have numerous constantly changing IP addresses. We strongly recommend you don't try to block our web crawler by IP address, as you'll most likely spend several hours of futile effort and be in a very bad mood at the end of it. The best way to save you time and frustration it just to add us in your robots.txt or contact us directly.
