`Diffbot-User`

Diffbot says Diffbot-User is for requests on behalf of a person browsing a URL in Diffbot software, in response to that person's input. The page does not say whether this token obeys robots.txt. The default adherence sentence on the same page is about Diffbot web crawls, which are the Diffbot token, not this one. The page's note on Extract and Crawlbot is about a customer's own user agent, not this card.
