Grief Prevention


AUTOMATICALLY PREVENTS ALL FORMS OF GRIEF, including build/break, theft, spam, fire, spawn camping, lava and more, so you don't have to undo any damage after the fact. No configuration or database required! Stop responding to grief and prevent it instead. Grief Prevention will solve your grief problems without requiring you to manage a roster of trained administrators, juggle 10 different anti-grief plugins, take away cool standard game features, publish a training manual / tutorial for players, or add explanatory signs to your world. You can also choose to integrate PvP elements into build design to finally get a PvP experience befitting a sandbox game about creativity.

Grief Prevention stops grief before it starts automatically without any effort from administrators, and with very little (self service) effort from players. Solve all your grief problems with a single download, no database, and no configuration step.

Official Servers (Try it for yourself!)

You can experience this plugin for yourself (as a player) by joining any of these public servers. :) We maintain these servers personally, which helps us catch bugs and spot opportunities for new features and improvements. Have fun!

More Great Plugins!

    • Limits how quickly players can mine valuables, based on their play time / values mined ratio.
    • Keeps your valuables in the ground, so non-cheating players can find them (unlike ore loggers).
    • Practically free to run, unlike the tremendously expensive Orebfuscator.
    • Most legit players won't notice, but xrayers will ragequit and move on.
  • Population Density
    • Automatically assigns new players to wilderness where they'll find other new players and plenty of space, wood, and ore.
    • Optional teleportation system which can't be abused by players to escape combat or save them from being lost.
    • Login queue to guarantee fairness when the server is full.
    • Optional reserved spots for administrators.
    • Automatically removes idle players when the server is nearly full.
    • Smart, multi-layered anti-lag feature set.

Coming Soon

These are my top priorities right now. It's not a complete list of everything I plan to do. :)

  • Automatically extend new land claims to cover entire vertical builds (even those which extend far underground). This means claiming an already-built construction from ground level or even the roof will still claim the entire structure, assuming it's vertically continuous.
  • Update /RestoreNature to regrow trees in biomes where they're expected.

Please Vote for Grief Prevention

I've also posted Grief Prevention on the Spigot site, where plugins are ranked based on reviews. If you love GP, please take a couple of minutes to give GP your rating and leave a short review. Better rating and positive reviews will help server owners who look for plugins on the Spigot site make the safe choice (GP) instead of downloading something sketchy or incomplete. :) Thanks so much for all your support!

    I know that to get rid of the "thin islands in the sky" is with the SeaLevelOrverrides, but what level do I set a flat creative world to?

    11.7.2 Update

    • Fixed /ContainerTrust not allowing farming in claim subdivisions.

    @LordKainzo: Go

    You can turn off the container protections globally in the config file, or you can completely turn off land claims for specific worlds (where you have instead other plugins like Factions or Towny).

    @chris_king: Go

    You were doing something wrong. :) The /AdminClaims command is for administrative land claims. They're free (you don't need to use your personal blocks) and anonymous (they don't reveal who created them to players). The reason for having a special admin claims mode is that some admins like to also be players, so this gives you the opportunity to create personal land claims (even big ones if you want using /acb) or anonymous administrative claims for free, depending on your preference or situation. All this is in the "how to guide for administrators" linked above.

    @chris_king: Go

    Use /adminclaims while having the golden shovel in your hand. Then you claim as usual (right click 2 times on the opposite claim corners). This creates an admin claim for the area (no claim points needed). We have very large admin claims protecting some this should work out for you. If access is needed for some parts of the spawn admin claim, you could create subclaims on it and trust (access-, container-, trust) people on the subclaims ('public' or 'all' for all players).

    Wish there were no limits at all for owners and operators. Frankly? This plugin is not anywhere NEAR powerful enough to claim my entire spawn area. Unless I'm doing something wrong..... I used acb (username) (amount[999999999]) to give myself more blocks... didn't work. I repeated this command like 15 times to give myself enough... and it still wasn't enough. I think it should be set by default that ops have no limit on anything while using this pluginthat should simply be default.

    I'm just having a hard time finding a decent anti-grief plugin for my spawn area that's all...

    My spawn is only protected by one block... and just so you know, config is still default. I made no changes, other than use the acb command.

    No stealing from ANY containers.\

    is this configurable, bigscary?

    Also - is this usable with plugins with town management like Towny/Factions?
