Is AFK farming allowed?

Yes. Each player is allowed to leave one account AFK on the server for keeping their farm's chunks loaded or AFK fishing. Other AFK farms such as an AFK nether wart farm or AFK ice farm are also allowed. However, setting up movement or mining scripts for your client to perform while you are AFK is strictly prohibited and directly breaks our "Do not Cheat" rule since it falls under client automation. Players found doing so will be banned.

If you plan on AFK farming on the server, keep in mind that you may be kicked due to a restart or other reason at any time. Restarts happen at least once per day. Also make sure to protect yourself from mobs and other players that could disrupt your AFK session!
