It seems to me the core of the issue here is a matter of assumptions and expectations. The staff's expectation is that those that enjoy their server are responsible for investigating and self-policing in unusual and extraordinary circumstances even when the circumstances themselves are not obviously extraordinary. The act of mining itself is anything but extraordinary. It's mundane, repetitive, and boring as hell.
The people playing on this realm have an expectation that things are made the way they were intended to be made. Not only is that our assumption, it is how we have been trained for years. It's as given as the boredom and repetivity of the act of mining. This is as true as can be, outside of the obvious extraordinary circumstances.
These five and probably another 100 untold are guilty of the sins of gluttony and greed. Are they insane? Probably. No more so then those that grind honor obsessively. Did any of them knowingly do wrong? That is highly unlikely but possible. The only way to be sure of that would have been to give them a warning.
As a rule, when Nostalrius ban's a singular person, they are open to revisting the issue and correcting a mistake if it has been made and that's cool. As a rule, when Nostalrius bans a "class" of people, it has never revisited it that I recall and that's kinda understandable. It would be scary to have the ground shift below your feet like that, wouldn't it? A similar situation was deciding what constituted abuse in LOS and rooftop camping. Once staff made their FINAL decision, everyone was cool with it, but there was some awfully wishy washy couple of weeks there.
Forget Blizzlike at this point. I suggest everyone stop using that term altogether except as a point of reference. Nostalriuslike is what is being shaped. I suggest Nostalrius quietly unban these people. I suggest, as I mentioned earlier, to deal with these uncertainties in the future by giving a warning....or give a one day ban for the particularly gluttonous/greedy person. Don't give bans outright to people who are just operating in the world that was created for them under seemingly ordinary circumstances.
