Keywords are: 'group leeching leeches leaches leaching' A leech is a group member who is idle or AFK for more than 20 minutes. The difference between a leech and a group bot is that a leech contributes nothing to the group - leeches do not assist, cast spells on others, tank, maintain minions, etc. Leeches can cast spells on themselves. If you see a leech in your group and wish to warn other players, you can report it using the 'report leech' command.
