PREVENTS all forms of grief - build/break, theft, spam, spawn camping, and more without a database.

    Stop responding to grief and prevent it instead. Grief Prevention will solve your grief problems without a roster of trained administrators, without 10 different anti-grief plugins, and without disabling any standard game features. Because Grief Prevention teaches players for you, you won't have to publish a training manual or tutorial for players, or add explanatory signs to your world.

    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 anti grief download, no database, and (for most servers) no configuration customization.

    Got a question? Having problems? Check the documentation!

    Got a problem or bug you can reliably reproduce? Or a feature request? Report it on the issue tracker!

    Also, you might be able to catch me/others on the #GriefPrevention IRC chat channel (or dumcord) for help (please state your question and exercise patience if you use this option).

    The Manual (Documentation)

    Even modifiyng the MaximumDepth it does not work with negative y !!!
    Just noticed that if I modify the claimdata to a negative Y coordinate IT WORKS but the plugin doesn't know how to put the - (minus) behind the number LOOOOL

    I will only give 5 star when you fix that... Because the plugin is perfect but this bug is so bad.

    The one star review directly below mine is attempting to punish the author because the user is too lazy to set up an account for GitHub, a *very* popular website which is often used to track issues on various project on this platform. Keep in mind the user paid absolutely nothing for this software. I have no idea where users get the logic to leave these types of 'reviews' but it's a very ignorant thing to do.

    Thank you to Robo and the contributors for maintaining GriefPrevention for such an extended period, you have serviced tens/hundreds of thousands of servers. :)

    I always used this griefprevention, but at a time the updates stayed away. Somewhere on the road i decided to use griefdefender instead, but i still hope this plugin gets a new heartbeat

    It used to work fine, after 1,17 0 update the developer doesn't care at this point and its abandoned.

    Version: 16.17.1
    It's do not work with piston in claim under y:0 and i self want it all over the world it's bether if you can do it everywhere
  7. Majekdor
    Version: 16.17.1
    This plugin was probably great 5+ years ago, but to be honest it's a joke at this point. Trying to interact with the code at all is a nightmare and there are bugs that have been around for 6+ months with no update.

    Really hoping a good alternative comes around because it seems like absolutely no progress is being made on this plugin at all.
  8. Mithrandir
    Version: 16.17.1
    Badly designed plugin in many regards, with some pretty decent code that makes up for it, as discussed and admitted by one of it's current devs, on a certain github discussion (can't find it now, seems to have been removed?).

    For what I can tell, I'd say It's not their fault, it's the original authors's. Current devs are trying to mitigate the design shortcomings in a future version.

    To be 100% brutally honest, I'm really hoping either another project shows up that can replace this, or a miracle version solves all the issues. If anyone knows of an already existing alternative, (besides precious stones that doesn't quite convince me) please let me know.

    I believe current GP devs need to know this. It's meant as constructive criticism.

    I still have GP on my server though, because I know of nothing better.

    Great plugin! Works perfectly on my 1.18 server with no errors. Thanks for creating this.

    Excellent plugin! Works with 1.18, but with errors on land claiming. Please update!
