Having read through this thread it sounds to me like you had your vendors permission settings setup incorrectly rather than a case of copybot. Let me give you an example, if I put out my nice big ball that I created and set it for sale but have it's permission settings as transfer, no-copy, no-modify well then guess what? When someone comes along sees my ball for sale and clicks buy/pay on it then that ball disappears from the land and is transferred to the new owners inventory. The only way I would then retain a copy of my nice big ball is if I had made a backup copy with full perms in my inventory otherwise it's lost to me for good. In such a situation I would not be the victim of a scam nor would I be the victim of a copybot. No, I would be the victim of my own stupidity or ignorance for not understanding how to set the permissions correctly on my items for sale and not keeping a good full perm backup copy in my inventory.
