Troll the Trolls Part 2 Instructions and Test

Trolls can view the posts made by everyone, while the posts made by trolls can be viewed only by other trolls. This might not be so clear from the instructions which say " Make sure that the trolls can only interact with each other.". Also, the solution which denies trolls to view posts made by non-trolls

bool display_post(AccountStatus poster_status, AccountStatus viewer_status) {
  bool poster_troll = poster_status == AccountStatus::troll;
  bool viewer_troll = viewer_status == AccountStatus::troll;
  return poster_troll == viewer_troll;
}

passes all the test. Any thoughts on this?
