As someone who is a mentor on Goblin who left the NN I will say my take. That network is beyond saving due to the clique of mentors who are power hungry. They have shot themselves in the foot because they are incapable of seeing reason. They ban anyone for having a dissenting opinion other than their own. Yes, I know exactly of the spammer in question. Who literally pops in everyday to leave a 4 page macro only to be kicked. He does this because of the fact the clique mentors blacklisted him because of dissenting opinions. If the person commits the crime of course ban. But a 24 hour blacklist is ridiculous. The mentors in control of that NN are not judges juries and in this situation Banners. You are there to help sprouts and welcome them to the game. By having a clique of mentors with an elitist mindset you are ruining the experience of sprouts all because a select few lack the maturity to properly handle dissenting opinions.
How to fix said problem: A SE moderator needs to launch a thorough investigation into the NN to understand both sides of the story and issue correction measures to the problem.
As of 2 years ago. I refuse to be associated with that cesspool of a NN and instead am an officer of an FC whose soul dedication is to guide sprouts new to the game. I find their passions and goals and above all put them in the best situation to succeed and have fun in this game.
