I'm kinda late to the party but in my view and I believe the view of most people, punishments should be based on either 2 of these criteria. Either
A) The punishment helps the community’s playing experience, ie punishing a player who is disrupting roleplay and negatively affecting the experience of other players present or
B) The player went against a moral rule, ie pedophilia or racism.
Well, it’s pretty clear the ban doesn’t help the community, and will especially hurt the community that Narthok has built up in Norland and Morsgrad. I don’t know Narthok as well as the other people in his thread, but speaking on behalf of the few of my friends that have recently joined the server, as players of Morsgrad Narthok is the leader we look up to and the one who leads us. He would always give us iron armor and other gear if we died without a second thought, and has truly established a thriving community in Morsgrad. He has poured what I can only assume must have been dozens of hours in writing roleplay for our nation, and 100s of pages. So seeing that it is evident his ban will not help the community, the only other explanation is that his forum posts went against the moral rules of the server.
I don’t know why Narthok got his previous forum warns, so I can only speak for the last one and the warn that ended up resulting in his ban, which has no basis. You could say that he broke a moral rule by promoting racist thought, but in fact, the opposite is true as he is making at the expense of someone who peddles in racist ideology. In fact, it seems that another mod believed the joke has tame enough and allowed the post to be made in the first place.
If Narthok is banned, then it is what it is. It will truly be sad to see Narthok go, but we will remember all that he has done for Norland o7.
