About this resource
Viper Anti-Dupe runs only on the server, so players install nothing. Its page states that it guards block interactions, hoppers, pistons, containers and incoming packets and lets you choose which duplication methods to block. It is a Fabric mod rather than a plugin and is published by the Fabric Server Essentials organisation under an all-rights-reserved licence, so read its terms before you redistribute it.
