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!

    • 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!

    In the config Claims.Mode, change the value to Disabled for worlds which you don't want people to claim land.

    I want to say a big sorry, it wasn't GP which was causing this strange glowstone glitch, I'll try to find the solution so I'll inform you if even that happens to someone else to know.

    Project "Ender's Infinty" coming soon and aims to be the best RPGMMO minecraft server.

    how can i deny a group of players to claim land? I have a plots world and a survival world on the same server. and i am able to server permissions for each world. so i would like to deny permission for one world but not the other.

    @bigscary: Go

    I am 95% sure that it's GP but today I'll confirm it and try to what is possible to fix, If'll do anything I'll inform you :)

    @Jikodis: Go

    You can find instructions on how to get your own latest spigot.jar file on the site. It requires a couple of quick downloads, then one command line. No coding.

    @Vtownhood: Go

    Like Jikodis mentioned, you can fix this by changing your config settings. I have a todo item to make this happen much less often.

    @Bobcat00: Go

    Placing one block is sufficient. Breaking has no effect.

    @robvan: Go

    Sorry no, there isn't one. I will add a command for you.

    @xDizasterCYx: Go

    This seems very odd - no one else has ever reported it to me. Are you certain there's no other plugin doing this to you? If you have only GP enabled, do you still have this problem? :(

    @Nentify: Go

    Yes, click the "files" link at the top of the page for older versions.

    @norsemines: Go

    Let me see if I understand - you visualize a claim, and your sign is replaced by a visualization block (glowstone, gold, wool, etc). When the visualization reverts (goes away), your sign is blank? Don't worry, your sign is safe - if you log out and back in, you'll get the server's version of the sign again, complete with your text. It might even work to right-click the sign with an empty hand (without logging out first). I will make a quick tweak to improve this.

    @wd40bomber7: Go

    That sounds like a bug I fixed recently - are you on a recent version? If not, please update and try again. Regardless, I'll try to reproduce this on the latest and investigate.

    @xSnowBlitzz718: Go

    Unlikely. I just don't have the free time to convert a project that took me 4 years to build over to another platform. :( Maybe if I had the kind of time I did when I started the project, but now I have a 2 year old and a second kid on the way. I'll keep refining this and possibly take on some small projects, but porting all of GP over to a new platform would be huge.

    A smaller job would be convincing the Cauldron guy to uncancel that project. ;)

    Not sure if someone did already but I would like to request this to be ported to Sponge.

    @norsemines: Go

    Yeah I've heard of this too, it's bad to hear that you have problems with GP, surely it's another plugin that it's not conflicts with it, when I firstly used GP it wasn't working to me because I was using another plugin called "LightningStick" and it was completely destroying GP, I created another server with GP and I was testing my plugins 1 by 1 but luckily I've found the problem really quick. Even the most irrelevant plugin can be the source of the problem.

    So, small bug that's been around for a while.

    A person with /trust and /permissiontrust on a normal claim who then attemps to /untrust someone else, gets a message telling them they don't have permission to do that. But the person is untrusted anyways.

    I would expect to get a success message instead of a failure message since that seems like the desired behavior.

    @xDizasterCYx: Go

    Fair enough :) I came here because the subclaim borders seems to remove sign-text where the border.blocks are shown :) E.g Place a sign, subclaim around it, and the border blocks will still remove all content of the signs it touches.

    I'm hoping this is a block update problem though, and not something stored.

    Your 'trailing glowstone' comment made me think, 'oh *noes* that as well?" :D

    My advice would still be to see if it happens around claim borders, by shovel or stick clicking. Or if it even drops glowstone dust/lamps.

    (the diorite glitch i mentioned would actually drop diorite from blocks that used to be stone, but that was caused by Spigot) :/ It was/seems fixed by a rebuild of the spigot jar however.
