You could do this: find this section around line 97 and add the part in red:

// get usergroups who should be displayed on showgroups
// Scans too many rows. Usergroup Rows * User Rows
$users = $db->query_read_slave("
	SELECT user.*,
		usergroup.usergroupid, usergroup.title,
		user.options, usertextfield.buddylist,
		" . ($show['locationfield'] ? 'userfield.field2,' : '') . "
		IF(user.displaygroupid = 0, user.usergroupid, user.displaygroupid) AS displaygroupid
	FROM " . TABLE_PREFIX . "user AS user
	LEFT JOIN " . TABLE_PREFIX . "usergroup AS usergroup ON(usergroup.usergroupid = user.usergroupid OR FIND_IN_SET(usergroup.usergroupid, user.membergroupids))
	LEFT JOIN " . TABLE_PREFIX . "userfield AS userfield ON(userfield.userid = user.userid)
	LEFT JOIN " . TABLE_PREFIX . "usertextfield AS usertextfield ON(usertextfield.userid=user.userid)
	WHERE (usergroup.genericoptions & " . $vbulletin->bf_ugp_genericoptions['showgroup'] . ")
AND user.userid NOT IN (X)
");

That's just for the admin section - if you want to delete someone from the moderator section you'd need to add another line to the other query.
