Better Anti-Dupe watches the items themselves. <br> It keeps a record of every valuable item a player gains and loses. When something's up, you are notified with a list of where <br> they put the items, and a [click to teleport] there. Install it and you are protected.<br>The defaults are sensible, and nothing is ever taken from a player until you decide it should be.</center> Will it work on my server?
