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.

    What steps will produce the problem: A sieges B. C who did not initiate the siege then tries to open B's chest.

    What I expect should happen: If C is not on trustlist of B OR A, C should not be able to access chest contents.

    What does happen: C can open B's chests regardless.

    It appears any third party can open chests and doors of the sieged party. Not the parties involved, but anyone else can open the chests.


    Logging out during siege will NOT punish user as specified in the config. Nor during PVP log out. Instead, these users are rewarded with the items that fell on the ground, AND the items that were not properly cleared during the punishment.

    is there a perm that can allow people to bypass the alpanumeric stuff and other griefprevention chat and also with the pvp protection logout?

    Updated to b282 from b213 and upon starting up the server everyone once again had negative claim blocks.

    Is there some way around this or is it impossible to update without sending everyone negative?

    Is there a way to protect unclaimed land from being modified in any way (such as place or destruction of blocks), unless the player is an op?

    I have a major problem, When Using the Cannons Plugin

    The cannons can partly destroy claimed builds, Its odd, griefprevention is kind of working, but not fully, an identical unclaimed build would be destroyed in one shot, a claimed build getting shot into takes 4 shots to take out a few blocks, but it shouldn't at all, here is my griefprevention config, Ive gone over every explosion and block breaking config and I cant figure out how its still causing some damage to claims.

    Do you publish/push your project to a public maven repo by any chance?

    • More Control over the Phantom blocks. Like a delay for disappearing in the config and maybe a cmd to disable them entirely for that user.
    • Make a config option to make the chest claim a one time thing. So that people don't always claim an area whenever they place a chest (which is kinda a pain)
    • A Rules File which lets you define the standard rules for every world. ((Because) the template file can not be accessed? :s)

    It would be awesome if you could respond to any of these :) Thanks a lot! :)

    Hey guys. I'm loosing my mind here with giving staff access to adminclaims etc.

    I'm using the groupmanager from essentials and when I give users access to /adminclaims or /naturerestore it does not work. I tried to add it in globalgroups, groups and lastly to users directly but it never works. If I op the admin in question it will work as op has access to everything so I know the plugin is working. It's just that the permissions wont work.

    I have 28 other plugins and permissions work there. Anyone?
