The server can be a bit confusing, there are multiple kinds of "rules" and they can interact with each other in different ways. This is the way I got it sorted for me:
Software -- This controls things like where you can dock.
Rules -- Determined by the Server Rules, and also by the ID you are using on a ship. This controls things like what ship you can fly (ID restriction), and also can include things like "dont dock on the enemy base, even if the software lets you." One of the rules is 1.2, which allows the admins to make judgement calls in order to preserve "server gameplay."
Role-Play -- This is an RP server, so what you do is supposed to reflect the way a character would act. Generally RP is reflected in things like rumor cards and info cards, but is also restricted by the rules and software (dont dock on enemy station). Generally the admins dont get involved with RP layer stuff, unless you happen to break a rule in the course of doing something else. You cannot have a Liberty Navy ID and decide you want to "go bad" and start pirating, for example, since its against the RP, plus its against the ID (no piracy), and also against server rule 1.2, so they would come down hard on something like that.
Part of the RP is that each house is the governing authority over its own space. As part of that, each of the house governments have House Laws that say what is legal and illegal in their own space. This defines contraband, import/export restrictions, fines, etc. If you choose to play in a house, you are participating in the RP governance for that house, and so choose to follow or break the "laws" of that house.
You mentioned a battleship in Omega-3. No house allows foreign powers to bring capital ships into their house space, and since Omega-3 is under the authority of Bretonia, they would be in the right to tell you to get out. I dont hink this is something an admin would have gotten involved with, since its at the RP layer not a rules violation, but it seems we're missing some details.
I saw a mention of ship names. Note that there is a rule against lulzy ship names, see rule 3.5. This is to preserve the immersive nature of the RP environment.
It's not so complicated once you get your mind around it, but it can be hard to grasp at first. Just ask here if you have any questions, people will advise and lawyer with you about stuff all day.
