Item dupe
In the middle of the hub, a staircase leads down to a portal to the Overworld. Opposite the portal, there is a manual item duplicator which works with any obtainable item and preserves metadata like enchantments. The dupe is based on a bug found by GiantWaffle and explained in this video by AntVenom, who was able to reproduce and exploit the bug. The bug is reported as, but Mojira policy requires dupe bugs to be private.

Usage
Use the portal at the entrance to the farm to go to the Overworld and back to the Nether a few times. The faster you are, the higher the chances of duplication. Then, check the comparators for duplicated items. A comparator that stays on means that an item was duplicated and you can take all items except one from the hopper pair.

If you want to duplicate a type of item that is not currently being duplicated, you can expand the farm horizontally to add a new dupe station of 16 hopper pairs. Make sure the new dupe station is within view distance (10 chunks) of the portal. Since the farm is based on server lag and hoppers create lag, this actually increases the efficiency of the existing dupe stations. Please be aware that because of, you may need more than one starting item.

Before creating a new dupe station, verify that it is allowed:

Rules
An item may not be duped using the method described above, if:


 * 1) the item is renewable using other methods
 * 2) the item is an ore block that corresponds to a renewable item (this is the case for all ores except diamond and quartz)
 * 3) the item is one of the following:
 * 4) * diamond
 * 5) * diamond ore
 * 6) * diamond block
 * 7) * beacon
 * 8) * dragon egg
 * 9) an item of the same kind (with the same string ID) can be  using an item that may not be duped

Currently, there are dupe stations for the following items:

History
Since there are no generic rules against bug using on the server, the item dupe was originally used to duplicate all kinds of items, including items considered valuable, such as diamond blocks and beacons, and items for which other farms exist, such as gold. Some of the players on the server then opposed usage of the duplication bug, and the following discussion did not lead to a clear result. As such, the legitimacy of the farm was unclear for some time. However, another discussion has since taken place on the talk page, followed by a vote to decide which items may or may not be duped (see the subpage for the results). The current regulations are the result of this vote.
