If someone in an official capacity as an authority sends a message to someone else, exercising said authority, then the privacy of that message is clearly for the benefit of the recipient. If the recipient chooses to waive the right of privacy, then I see no reason why they shouldn’t be able to make public that message.
Its like in school, when a teacher gives out grades, or comments, privately, the student can share what they were given, because the privacy was for the benefit and consideration of the student, not the teacher. Presumably, anyone acting in an official capacity as an authority figure, exercising said authority, cannot be sharing any personal or private information that is intended to be kept secret for their sake, since if its done in official capacity, it should be public record.
Im not a mod, make any regulations you want, doesnt matter to me, this just seems to be the way it ought to be.
