Grief Prevention

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!

  • A /ignore command for players.

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!

    Is anyone else having an issue that random players are given full access to other players plots even without permissions? because right now i have 12 people who have full admin powers without the permissions.

    If you add this in, it should probably function similar to how Endermen are controlled.

    I run a classic survival server, and almost all of my users complain to me about this happening. It does happen on a large scale. They literally spawn wherever carrots are planted and eat 1/3-1/2 of the yield. While rabbits aren't players, they do grief in this manner, I suppose xD If you don't want to add it in, that's fine, I was just wondering :P

    @CKGAR: Go

    Wow, I didn't even know they did that. No, I don't think I will - since you're in control of your land, I think it's up to you to keep your rabbits away from your carrots. :) Unless you can imagine a scenario where a griefer could somehow use rabbits to wreck your carrots? Maybe if he found a rabbit and lead it over to your nearby, unfenced field of carrots - but that's very opportunistic... thoughts?

    Is there a way to prevent rabbits from eating carrots in land claims? Thanks.

    11.5.2 Updates

    • Disabling creature protections in the config file will now allow villagers to be attacked without permission inside land claims.
    • Added a new config option so that server owners may allow anyone to trade with villagers, even in land claims where they have no permissions.
    • Fixed sign placement entries in server logs not including the placing player's name.

    @GodsDead: Go

    You should have it in your configs already. See for example:

    GriefPrevention.Abridged Logs.Included Entry Types.Debug

    @The_PC_Tech_Guy: Go

    Yep, yaml is awful that way. :\ Sorry! I might have already fixed that for new servers. I'll check.

    @Bohi250: Go

    Yes there is, see for example:


    Note that for this to work, you have to have your pvp worlds listed under the "pvp worlds" config node. It works this way because sometimes server owners like to have separate factions pvp and gp pvp and survival games pvp worlds, so it's important that GP is able to limit its pvp rules to only specific worlds.

    If you check your config and still can't figure it out, then please use to share your config settings here so that I can investigate for you.

    How do i disable pvp in claimed areas? There's no config for that

  • Avatar of The_PC_Tech_Guy The_PC_Tech_Guy May 02, 2015 at 07:56 UTC - 1 like

    So I apparently made some invalid YAML and had GriefPrevention reset my messages.yml : / Anyways, I found a typo with the default messages.yml:

        Text: Sorry, buying anhd selling claim blocks is disabled.

    @bigscary: Go Oh cool, Ill throw some of the commands into the whisper command config then! How do I set the config to say what to track? were new options generated? Im guessing these options were not added to old configs! If so do you have an online version of the config I can copy into mine please?

    11.5.1 Updates

    • Added per-defender /siege cooldown.
    • Performance boosts for equipping the golden shovel and delivering claim blocks.

    @ElijahLee: Go

    Sorry for the trouble - I will investigate.

    @DanielMuhlig: Go

    No, but you could give them one-time bonus blocks as a group with /acb [permission.node] <numberOfBlocks>.

    @EpicATrain: Go

    Thanks for that info! I will investigate and fix.

    @Petes21: Go

    Unable to drop items - that could be if your world is set as "creative" mode in your GP config. As for the others, that sounds downright scary. Maybe try rerunning buildtools.jar to make sure you're not using some corrupted spigot jar? You might also try disabling plugins one at a time until you can reproduce your issues while only ONE plug is running, so that you know for sure you've got the right plugin.

    @samsvenson23: Go

    Isn't that normal vanilla behavior? Right-clicking uses the item in your hand?

    @The_PC_Tech_Guy: Go

    Thanks, I'll get that fixed.

    @GodsDead: Go

    It uses the whisper commands from the spam configuration section. Even if you have the anti spam turned off, the logger will still use that setting to decide which slash commands to log in the abridged logs.

    The config already has "what to track" options, and they're not all on by default. Try turning on the debug mode and the admin mode, then let me know if you still want more.

    @CaptDarkStar: Go

    The /acb command DOES add or remove blocks from the total by adding or removing them from the bonus blocks. The /setAccruedClaimBlocks command sets accrued blocks to exactly the amount you want (not changing bonus blocks).


    • Add 500 /acb johnson 500
    • Remove 500 /acb johnson -500

    Many servers use /acb to award blocks for contests, cool builds, votes, or buycraft purchases.
