Prim SLicing

Would it be possible to keep someone from Prim Slicing through a wall... by adding an option that you can check that says Something like PrimBlock, So that they wont be allowed to sit on a box and move through the wall? I had a store on my land and a piece of it was for employees only, it had an elevator that only employees can use, and a lock to keep people from flying up the shaft, i didnt want to ban people or keep my land or allow it to only those who are on my access list. But everytime i went their some fool Prim Sliced there way into the room and looked at the "new Release" before they came out or messed up the place =(

There currently isn't a feasible way to do what you describe, unfortunately.

I suppose you could use a Resident-created security system to provide warnings and teleport people in an unauthorized area home.

Access lists are exactly for the purpose of restricting access to your land. Wish there was an easier way for you (apart from getting a private island and hiding it). That's one of the tricky things about SL: we allow for a great range of movement, but that also makes it tough to curtail where curious avatars may probe.
