Grief Prevention


AUTOMATICALLY PREVENTS ALL FORMS OF GRIEF, including build/break, theft, spam, fire, spawn camping, lava dumping, chat trolling, advertising and more, so you don't have to undo any damage after the fact. It even teaches players how to use it so you don't have to! 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 creative building.

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.

    Thanks @ThisUsernameIsMine and @lucasbuck2 - both answers were wrong as per the location, but the property mentioned by lucasbuck2 DOES exist in plugins/GriefPreventionData/config.yml so I managed to resolve by using this...

    @Kahanamoku78: Go

    I believe it is in your wrold.yml under world config. Look for the line: WildernessWarningBlockCount

    Navigate into the GriefPrevention\WorldConfigs\ folder and set WarnWhenBuildingOutsideClaims to 'false' for each world

    Is anyone else having a problem in 7.8 where abandoning a claim doesn't remove the liquids?

    I'm wondering how it works within op's.

    Mostly because I'm the owner of the server and I have a claim for my house, and the op's can still build/destroy blocks, but when I /transferclaim to make claims for them I can't build/destroy on their claims, yet they still can on mine.


    Nvm, I found it. I was respecting people's claims, but they weren't. It was all /ignoreclaims


    Goddamn annoying, having Admins messing around on my plot. I wish I could disable their use of /ignoreclaims. Imma need to get a permissions plugin, anyone know a good one?

    I've been having an issue recently with subclaims being reset when restarting the server. I've noted a ticket, but no responses, upvoted it anyways. Is there a setting that is doing this or some way to prevent it from happening? Seems to happen on Admin/Player claims alike. Using GP build #282 from the Jenkins build site. Would love to keep using this plugin, but the issues have prompted me to try and write one that works similarly, without the huge issues slowly giving players a bad taste about my server.
