You and your basemate Quigybobo were banned for duping items. As far as i know, Quigy has been banned in the past for duping and given that you both use voice comms im aware you would know that too. Since this is the second ban, your appeal is denied on the basis that you were well aware of the rules yet your group still chose to test the waters for a second round. You were given a chance to not dupe again and given you have, we have no intention of believing you wont do it a third time.
If you want to dupe, you are free to do so on another server, not ours.
