Did they get permission from Github to scrape their website for the content they have put up? From the terms of service: 4. You must not modify, adapt or hack the Service or modify another website so as to falsely imply that it is associated with the Service, GitHub, or any other GitHub service. 5. You agree not to reproduce, duplicate, copy, sell, resell or exploit any portion of the Service, use of the Service, or access to the Service without the express written permission by GitHub. Although I guess if the GitHire guys never used Github they aren't bound to those terms.
