I was reading the scam post´s and read one thing that stayed in my mind(sorry i can´t remenber the person that said it first).. why not create a ownership for item´s just like the minig claim´s? I know that would make alot of "little paper´s" in your inventory but they could create something like a ownership´s book... And even a button to re-claim the item so that wen you wanted you can take your item back... That would solve most of the scam´s if not everyone of them...
