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.

The Manual (Documentation)

If you're new to Minecraft servers, you can learn how to set up a Minecraft server to run GriefPrevention and other plugins here.

If you're not running a 1.8 or later server, you can get older builds of GriefPrevention on the BukkitDev page.
