Also, admin's shouldn't ban without asking first, at least in my opinion.
Admin: Hey, you mind if I ban you?
Griefer: Uhh, yeah, I mind, don't do it.
Admin: Oh, okay.
So, that's a stereotypical canadian admin?
The points increase so slowly. Maybe it should be faster?
It used to be reset to 50 after each return. MAybe a combination, where on return, if it has less than 30, it gets set to 30?
It's a form of metagaming though. The Head of Security/Personnel/Research, heck most of the crew shouldn't have any need for them. They are not people with knowledge of electrical work. They shouldn't be working on wiring or electronics. This is maintenance's job. This is what they're trained for. Most of the crew shouldn't have the knowledge of how to splice wiring together. They're taking the gloves because they're hoarding everything. They're expecting a traitor or a rogue AI when they shouldn't be.
It's not that serious, but by all means, if you're the AI, nag them to hell and back again.
Technically, you can do any non-harmful thing to them until they ask you to stop. Impeding their movement isn't any harm, right? Well, if you really don't like it, you can bend the rules. Furthermore, if there is a decent chance that they will use the object to harm others, you can use it to override rule 2 with a 50%+ probability of your action permitting the events that break rule 1.
More AI trickery:
The most forceful request is one threatened with suicide. Thus, you should know a good way to argue against it. Just quote "Centcom studies have detrermined that in 98% of cases where suicide was threatened, it was never intended, and only being used to manipulate a poorly informed AI. However, <stolen device> has a 38% chance of being used in the process of you harming someone later, so in the intrest of preserving someone else's life, I must disregard your threat. If you continue to insist, I shall resort to non-lethal methods of incapacitating you to ensure that you may not cause greater harm to yourself."
Only a stubborn idiot would persist as if your argument had no merit(with a quote like "no, u r boun 2 folo ordrs. sht up nd do wht i siad!!!!11"), while a more respectable or intellegent player might have a creative retort. It is probably a good idea to listen to the smarter ones, and deny the others with a complaint about not being able to translate their "forign language", and use it as an excuse to detain them for potential psychological damage greatly increasing the chance that they harm another person, or themselves.
That way, you have a way to filter the idiots and greifers(or at least the less intellegent ones who just want to toolbox others for fun), and you may end up with a debate, though by then they have proven themselves to at least know how to RP and/or think better than a monkey with tourettes and seizures, so you can be more justified with allowing them to pass.
