Dupes

Admin Approach
The server runs Paper which attempts to stop many dupes. You may have find dupes which are not patched.

If players discover a dupe on the server and exploit it, great, Get rich. Admins won't take away items from your inventory or destroy your dupe stashes.

If a dupe is discovered, players should exploit it as much and as quickly as possible, as once a dupe goes public a patch is likely from Paper.
