I've always hated hiding information behind some sort of purported "moral high ground" of gatekeeping uncredentialed individuals from knowing the answers to material. Information wants to be free. Everyone who encounters public questions with private answers can and should publish solutions on an uncensorable service (multiple mirrors across archive.org or archive.is or Gists).
