I see your point of view and I agree in theory. However, in practice, the NN should probably just be deleted and nothing of value would be lost. I lasted about a week in there before I left when I was new. On Zodiark at least, a group of high level players used it to argue about game balance, 80% of it was in non-English languages and if an actual newbie asked a question, they would either not get an answer or get told off for interrupting the conversation. Honestly, the entire mentoring system is garbage, but NN especially.
