Yeah, they can just make 10 accounts and levels those chars like boss to 75, but searching item for 3k each? As Cliph say : "Good luck with that". Unless you have no life and use DD, that would be impossible. Even IF you can do those, they won't care. (I also won't care of that. I still have my real life thank you.) Also not all items can be gotten by low levels player. (some of the items are drop from high level monsters, then again they can buy from other player...)
