Someone is “name squatting” our registered trademark. We filed a formal trademark complaint on August 18th, 2017, and were told usernames are first-come-first-serve basis. We tried to explain at the time that the name was not being used, but that didn’t help. Its been almost three years since we reported the issue and the username is still not being used. Github has a no “name squatting” policy as detailed here: https://help.github.com/en/github/site-policy/github-username-policy so we’re hoping that the policy applies at this point.
