So there's a sort of anti-cheat mod called Server Characters by mod author Smoothbrain which completely prevents server hopping - not all mods are bad 🙂 - not to mention AzuAntiCheat by mod dev Azumatt, which prevents all cheat engines from being secretly ran and either discretely or blatantly destroying the multiplayer experience. In addition to ProtectYourSeed by mod dev Coemt which prevents people EVEN admins from running 3 game breaking dev commands. Honestly, not sure i'd ever run a multiplayer experience without these three at the core to keep things fair for all.
