Those are the best set of rules I've ever seen! Great job Pete! I lol'd hard when I saw that.
If only these would actually clear up the issues.
Well, they do. The thing is, "common sense" can be different for different people, and that's why Ops need to be handpicked. If a guest has a different "common sense", explain to him what he's doing wrong (warn). Then prove to him you have the control, and that he MUST use your same "common sense", (kick). Finally, if said guest just won't change his "common sense" feeling, we should just avoid him getting on our server, (ban). He can go find a server where trolls and griefers are allowed.
