Tutorials/Griefing prevention

Griefing is the act of angering people in video games through the use of destruction, construction, or social engineering. Popularized in Minecraft by "professional" teams, griefing has become a serious problem for server administrators who wish to foster building and protect average builders.

Rise of Griefing
Griefing is far from a new phenomenon in video games. Frustrated users or mal-intentioned gamers have oftentimes tried to cause grief among other players in multiplayer servers they join. One of the most famous groups to do this was Team Roomba in their Team Fortress Griefing series that was picked up and popularized by the Escapist Magazine.

Minecraft Griefing Teams
The creation of teams producing their own videos has revolutionized Minecraft griefing. Since the popularization of griefing by notorious teams such as Team Avolition, numerous griefing groups have spawned and created a strong fanbase for the topic.

Fortunately for server administrators, who wish to counter griefing at every turn, the popularization of griefing has pushed the creation of numerous anti-griefing tools and techniques.

Common Griefing Methods and Prevention
There are other forms of griefing, however they are simply variations on the ones listed above. Essentially, if moderators are attentive and the server is equipped with the necessary plugins, a server can be very secure from griefing.

Griefing Clients
While modifications to Minecraft clients are fairly popular with legitimate mods, griefers also often employ client modifications to aid their efforts. Common client "hacks" include:


 * Flying: Not necessarily used just for griefing, this hack gives the user the ability to fly similar to as if they were in Creative mode at adjustable speed levels.
 * X-ray or Wall-hack: Stops the rendering of any block besides ones desirable to the griefer. This hack is often used to find chests or valuable minerals such as diamond.
 * FullBright: This hack lights up all blocks as if they were in direct sunlight, even in pitch darkness.
 * NoFall: This hack prevents damage from being taken when falling from high areas.
 * Sneak: This allows griefers to sneak indefinitely and move at a faster pace. This will keep their nameplates hidden behind walls just as if they were holding the sneak button.
 * Speed Breaking or InstaMine: This allows for griefers to break blocks at a much faster speed than normal.
 * Aura or Forcefield: This auto attacks anything from players to mobs within striking range.
 * Nuker or Annihilator: This destroys all blocks within reach radius automatically.
 * God: This makes the user invincible. Almost all versions of this hack have been patched.
 * Step: This modification allows for the user to simply walk up blocks and small cliffs (up to 9 blocks high) as if they were half steps.
 * Build: Build hacks are simply modifications that instantly place blocks in a predetermined pattern. Common builds include cubes, pillars, and platforms.
 * FastPlace: This modification eliminates the normal delay when placing blocks.
 * Freecam: This mod allows the user to separate himself from his body and fly around to scout out areas. Since infinite reach was patched, the user of this mod cannot affect any blocks outside his/her reach radius.
 * Spam or Flood: This allows the client to send a huge number of chat messages to the server.

How to Prevent Griefing
While there is not much that can stop a determined griefer, there are ways for a server to mitigate the risks of being griefed. The following is a list of steps server owners can take to try to keep their server protected:


 * Protect the server with appropriate anti-griefing plugins.
 * Do not let administrators abuse their power (this can incite anger in users and bring about griefing). Also, be cautious in choosing who to give administrative permissions to begin with.
 * Be careful what permissions to which people have access. Owners can limit access with Server modifications.
 * Be careful where the server is advertised. While more exposure means more members, it also means griefers can find it just as easily.
 * Become familiar with what griefers are capable of doing. There are no hacks "to gain op" or "delete the server". If one takes the time to learn what is possible (by watching griefing videos from popular teams and reading griefing forums), you will be more able to counter it.

Anti-Griefing Server Modifications
While there are many people creating grief-friendly client modifications, there are equally dedicated programmers creating server plugins to foil their attempts. Using the popular and extensible Bukkit server software and other Server Mods, programmers have made numerous add-ons to enforce correct client behavior. There are plugins that allow administrators to log and rollback all edits done on an individual basis, employ jails to trap griefers, and even protect certain blocks or entire chunks.
