I can copy items I buy that say no copy as long as....

I found a small bug/ or in some peoples eyes could be a big one.

Here is the decription and how to replicate the problem.

I bought a sword that said buyer can modify, buyer cant copy.

Now I found this by mistake kinda, I wanted to change the sword a bit, so I delinked the whole sword. I deleted the previously designated parent object and made my own. I modified it and relinked it with the new parent object as the parent. And i liked what I did so much that I just had to try to copy it so I could wear 2 of them. Well since I am posting here you can say I was able to copy it with no trouble.

Now this raises a concern. Xavier and I have been working on a boat for some time now, and if he decides to sell it. and being the great guy he is allows the buyer to modify it after they buy it but doesnt want it copied. The potential buyer can easily "Hack" switch the parent with one they create, then grab the script from our parent delete our parent, and then create a parent inserting the script. then there ya go its now copyable and sellable, in fact it now appears to the program that they are the creator and own the boat.

This is just an example it could happen to anyone, I did it, I already informed the person I bought the sword from as to my ability to do this and that I wont sell the copy as I have no right to.
