Agreed. I just reported that account (https://github.com/dmcahelper) for submitting spurious DMCA takedown requests. GitHub personnel responded promptly:

  Hi Justin,
  
  Thanks for writing in. We're looking at the account.
  
  All best,

GitHub is listening. Please consider reporting this account, which can be done via the link above. Look for Block or report user link under the user description at left.
