What is deop?

Deop is a term used in Minecraft that stands for "de-opped". It means removing a player's operator status, which is the ability to use commands that control the server. Deop can be done by typing "/deop [player name]" into the server console or through the in-game chat when given the permission to do so. Deop is usually used when a player misuses their power or to prevent griefing from occurring. In some cases, a player may ask to be deoped if they no longer want the responsibility of being an operator.
