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!

    • 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!

    @TheSupaSmiley: Go

    You have to update your server to a modern 1.8 version. Older versions of 1.8 have a problem with armor stands.

    @RockStarTragedy: Go

    Sorry, there isn't yet. I have it on my todo list to add.

    @atvar8: Go

    I'm only guessing wildly here - make sure your server is 1.8, and you got it from the site by running their buildtools.jar app. Also after you install any plugin, you have to either reboot your server or run the /reload command to make it start working. If none of this helps, go to your latest server log file and look for details about the problem.

    @Isiah59: Go

    Buying/selling/renting land claims isn't part of the base plugin. There MAY be a working extension plugin out there to do it, but if there is, I don't have a link. Maybe someone else who reads these comments can help you better. :)

    @ilikecorn500: Go

    To grant access to buttons/levers for ALL players in a land claim, stand in that land claim and execute /accesstrust public.

    Great plugin! I'm having a problem. None of my default users can press buttons for a command block in an admin claim, but I can. Is there a way I can fix this? I'm running the latest Spigot and bPerms.

    @RockStarTragedy: Go

    you could use my plugin to find 'unused' claims 1.) via Dynmap or 2.) csv file export

    JDynmapGriefPrevention: GriefPrevention Addon with Dynmap Support (if available)
    JWebConsole: Colored WebConsole for Minecraft (PHP) - nice, simple, useful

    @bigscary Hello. First of all, congratulations on creating such an amazing and successful plugin!

    I co-own a private economy server that's going to be up soon, and we were planning on making cities, some where players cant build but can buy homes, and some where they can build their own homes, Admins are going to be controlling most of the claims and giving these areas to new players on the server, in plots. Kind of like selling land or houses in real life.

    Is this possible?

    Thanks again.

    @bigscary I've played on several servers that use Grief Prevention, so I can definitely say it's a wonderful product..

    I'm recently getting into the Administrator side of things (my own server! Woohoo!) and I decided upon Grief Prevention to hassle my players the least and to keep server resource usage to a minimum to keep lag down...

    The issue I'm experiencing (I haven't been able to find any cause or fix for this anywhere..) is that the plugin loads, but doesn't FUNCTION. All commands receive an "An internal error has occurred" error... Any ideas?

  • Avatar of TheSupaSmiley TheSupaSmiley Aug 24, 2015 at 23:13 UTC - 0 likes

    Loving the plugin! Really helps to keep the griefers off our tail!

    One problem we've been experiencing is 1.8's Armor Stands not being protected. People are free to take armor or even the stand without being given any permissions in the claim. Is there a way to change that or is it a bug?

    Thanks for taking the time to look at this! ^-^

    Hi there! I really enjoy the plugin it has been a huge help to the server. I just want to ask one question.

    Is there a permission node that I can give to my moderators that show the "last login" line for users claims? We have a system that after 60 days claims expire, and mods check up on existing claims to prepare for claim expiration. I don't want the mods getting any power or ability other than just being able to see the last login time. If this is currently not do-able, may I offer this as a suggestion? Thanks for your help in advance!

    Update 12.2 is here! GriefPrevention is rated #2 on the Spigot site. Please help it reach #1 by leaving a 5-star review. :) Thanks!

    @user_413872: Go

    Update to the latest. Looks like McMyAdmin is installing an outdated version. :(

    @FrankTheProGamer: Go

    The auto-complete for commands isn't controlled by any plugins. Consider complaining to the spigot team or disabling the autocomplete (I think it's in the server config file).

    @AriKira: Go

    Yes. Each server can specify a different database on the same database server in its GP config file.

    @CloakedAlien: Go

    It could be that it's my fault and there's something I should fix on my end, but it only occurs on atypical database setups like yours. I'd have to totally replicate your whole setup to be sure (plugins, database software and settings, possibly hardware...). It's just too much. :(

    WT a nice plugin! And i have a question... Could i use this plugin for multiple servers with the same mysql... Just like server A connect to MySql, Database is GriefPrevention. And server B also connect to MySql, Database is Grief Prevention. But every server's world name is different! server A is survival-1, Server B is survival-2
