Moderators 
Moderators are users appointed by the vBulletin site administrator who are put in charge of maintaining one or more channels. Moderator responsibilities include deleting offensive or inappropriate posts, pruning old threads, and banning users from their channels. Moderator responsibilities are “assigned” to moderators through permissions.

Many of the product functions important to moderators are located in the vBulletin Moderator Control Panel (ModCP), a menu of your vBulletin installation and its submenus. The ModCP is a scaled-down version of the AdminCP.
