Order of prim return when land is full?

In what order are prims returned when the land's prim allotment is exceeded? I have recently had vendors returned from land I don't own, when some new junk prims were added by visitors.

I also had some of my own prims returned once on land that I did own, when I let a friend set up a house there and she added too much furniture, exceeding the prim limit.

Theoretically, you should not be able to add prims to land that is full, but apparantly when you get close to the limit, this can happen.

What determines the order and priority for which prims are returned?

Thank you Llauren, that was interesting...

But, it wasn't really what I was asking about.

My question has to do with what order prims are returned when the allowed prim allotment is exceeded on a parcel of land. This occasionally results in some prims being returned that had been there prior to the limit being exceeded.

Until recently, the logic for what gets returned was full of convoluted exceptions. As Kelly stated:

Previously we would allow the rez and then follow some crazy logic to return something on that parcel - usually the thing just rezed, or another recently rezed item. Now the rez is blocked which saves us an object return and more effectively stops grey goo from rezing beyond parcel limits. This change is live.

I documented cases where a person could drive a vehicle onto their own parce, which was so large that the vehicle itself could never fit on the parcel, and dismounting from the vehicle retrurned almost every prim on the parcel, except for part of the vehicle, and a few odd prims.

Kelly just changed the behavior, apparently. But before that, I know it was quite possible under some circumstances for far older content to get returned when an overly large mass pf prims attempted to rez on a full parcel. Kelly's change is supposed to fix that. We hope...

It SHOULD be Simplicity it's self. Like Unionized Seniority. "Last on, First Off". why is it so hard for LL to do things like that? When a Sim is overloaded, the system should simply Remove the Most Recently placed items.

My problem i Imagine, is that i think Too logicly to be either a programmer, or a Game designer.

Well, Angelique, it should be even easier than that, in my opinion. In addition to what you describe, you should never ever be able to add prims to a parcel that would put it over limit.

I understand that they intend (hahahahaha) to make that the case *most of the time*, but I believe that I remember reading that it's still possible in edge cases. And edge cases become attack vectors

I am pleased that they are working on it, but I do not have confidence that it will be adequate any time in the very near future.

That does explain why it didnt seem to make sense regarding which objects got returned.

Thanks Y'all.
