Important
This is a fork of GriefPrevention from TechFortress. The goal of this fork is to completely overhaul the entire codebase to make it cleaner, remove obsolete code, and generally make it more maintainable. While it tries to keep the features of the original plugin, it does remove the chat moderation, as I think this should be done by a chat plugin specialized for that.
Stop responding to grief and prevent it instead. GriefPreventionNG stops grief before it starts automatically without any effort from administrators, and with very little (self-service) effort from players. Because GriefPreventionNG teaches players for you, you won't have to publish a training manual or tutorial for players, or add explanatory signs to your world.
This GriefPrevention fork is compatible with Paper and it's derivatives.
