Some reasons harm the banned person much more than necessary. Grooming is a great example of this. By getting a network ban, the highest possible punishment CubeCraft can hand you is already given. Then also naming that they groomed can harm the banned person in real life instead of on a gaming platform. A lot of people have experienced the power of the more toxic communities of Minecraft and CubeCraft when it comes to this, where they get doxxed and threatened harshly. For doxxing, all these reasons do not matter, hence I suspect most of the time the reason will be kept private if it harms the person who did whatever they got banned for even more
