Good one, no one likes dupers XD ! And there was only one real duper. It was autorune. Used to dupe party hats and rune 2h's. If your wondering how item duplicators work read this:
People download artmoney to trick people how rich they are or edit some odd value for comedy. What autorune was different. Artmoney and TSearch are what you call memory editors. They edit cirtain values of anything. But autorune sent server pings with information to an exchange of nothing for somthing. I wanted to make a java based item duplicator. This is how i'd do it.
Most 'stat editors' and 'item duplicators' are really just virus infested memory editors. With this device it will send the same request as buy 1 from a general store. When an exchange is made it looks like this:
If we can make an applet that edits that and sends the same command for a different price. An item duplicator will be made. I've developed the idea. Private server programers: UNITE!
