NO OP
by VictorWinner
NO OP is a Fabric server mod that blocks anyone from gaining operator privileges on a server for 1.20.1.
What it does
Once the mod is installed on a server, the OP setting is permanently blocked, so no player can obtain operator rights. Every player's permission check comes back as Level 0 inside the mod, including accounts that are already listed as operators, and the server empties its ops.json file on each startup. The server console keeps full control, so the operator can still administer the server from there.
