What is GriefPrevention?

GriefPrevention is a Minecraft server plugin which 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 (the default configuration is sane and will likely be all you need, but of course everything is configurable and fine-tuneable to your liking).

Feature List

• No database or world backups required.
• Extremely efficient CPU / RAM usage.
• Land claims are easy to manage.
  • Players create and manage their own land claims, so you don’t have to do it for them.
  • New players get automatic claims around their first chests so they’re protected even if they don’t know how to create land claims yet.
  • Players who ask for help in chat get an instant link to a demonstration video.
  • Resizing claims and creating new claims is done with ONLY the mouse, no slash commands (slash commands are also available).
  • When a player appears to be building something nice outside his claim, he’s warned and shown his claim boundaries.
  • Claim boundaries are easy to see, and don’t require any client-side mod installation.
  • Extremely easy-to-remember, single-parameter slash commands for giving other players permissions.
