In addition to the quiz and /rules (a sign for /rules was recently added in the quiz area, if I recall properly), there is also the rules page on the forums:

Grimm, I think, did a good job of trying to help players better understand what staff looks at when dealing with a rules break as well as punishment levels, and deeper explanations of some rules. Now, perhaps the severs announcement system should include a rotation that refers to this page. That might help clear up some issues. However, that still requires the player to take the action of clicking the link and reading it.
I think it might also be time to dissuade people of the illusion that the server is somehow under the same rules and guidelines set down in the Constitution of the United States. It's not. Not only is the server not hosted in the US, it can best be describe as its own online nation with the staff standing in as a governmental body. Now, you can take that however you want, but it generally means that The Founder and original staff established the rules, the existing staff are there to enforce and execute those rules. Those who willingly immigrate to the server, like immigrating to another nation, are expected to follow those rules. Those who cannot or will not get deported (banned). The server also is a open border. Everyone is free to come here. Once they do, they fall under the server rules while they are here. This is part of the reason for the tutorial, /rules, and the above forum post. People are also free to leave if they wish. Anyone who feels that they cannot follow those rules or dislikes the way the rules are enforced, need only hit escape followed by "save and quit to title."
I realize that sounds harsh, but that is the truth of the matter. I find all this squabbling over rules that have existed longer than most people have been on the server to frankly be a nuisance and waist of time. I have seen a lot of forum posts lately debating or frankly, crying, over the rules of the server or how staff implements them. While I don't want people to feel unwelcome on this server, simply put, if you can't play by our rules, then this might not be the server for you.
Just enough of a Bastard to be worth liking.
