Since GH URLs are github.com/<name>, you also can't register usernames like @login, since that would cause a conflict. However, @case-studies and @customer-stories both are content pages (well /case-studies redirects to /customer-stories) and users. Those two users also cause weird things when interacting with the website and API.
