我发现了这个：

Exclude Users from Members directory on a BuddyPress based social network

以下代码将允许从members目录中排除用户。他们仍将列在与他们是朋友的其他用户的朋友列表中。

add_action(\'bp_ajax_querystring\',\'bpdev_exclude_users\',20,2);
function bpdev_exclude_users($qs=false,$object=false){
 //list of users to exclude

 $excluded_user=\'1,2,3\';//comma separated ids of users whom you want to exclude

 if($object!=\'members\')//hide for members only
 return $qs;

 $args=wp_parse_args($qs);

 //check if we are listing friends?, do not exclude in this case
 if(!empty($args[\'user_id\']))
 return $qs;

 if(!empty($args[\'exclude\']))
 $args[\'exclude\']=$args[\'exclude\'].\',\'.$excluded_user;
 else
 $args[\'exclude\']=$excluded_user;

 $qs=build_query($args);

 return $qs;

}

how to hide admin activity on Buddypress activity?

add_action("plugins_loaded","bpdev_init_sm_mode");
function bpdev_init_sm_mode(){
if(is_site_admin())
remove_action("wp_head","bp_core_record_activity"); //id SM is on, remove the record activity hook
}

UPDATE

了解如何执行此操作。这是buddypress忍者和恢复管理栏的组合。忍者插件可以工作，但目前无法在新的管理栏中切换。因此，您可以临时激活旧条，切换隐藏模式，然后重新激活新条。

            //then remove the last activity, if present
            delete_usermeta($bp->loggedin_user->id, \'last_activity\');
    }
});

// "Not recently active" yazısını super admin için kaldır

    global $bp;
    if ( bp_is_active( \'xprofile\' ) ){
        $last_active_bp_string = __( \'Not recently active\', \'buddypress\' );
        if( ($last_active_bp_string == $last_active) && is_super_admin($bp->displayed_user->id)) {
            $last_active = __(\'Network Admin\');
        }
    }
    return $last_active;
});

刚刚从buddypress 1.9.2中删除了管理员用户

我是这样做的：

我的管理员用户id2

在文件中：buddypress\\bp-members\\bp-members-template.php

查找第292行\'exclude\' => false,

和更改false 至您的用户id我的案例2 :

 // type: active ( default ) | random | newest | popular | online | alphabetical
$defaults = array(
    \'type\'            => $type,
    \'page\'            => $page,
    \'per_page\'        => 20,
    \'max\'             => false,

    \'page_arg\'        => \'upage\',       // See https://buddypress.trac.wordpress.org/ticket/3679

    \'include\'         => false,         // Pass a user_id or a list (comma-separated or array) of user_ids to only show these users
    \'exclude\'         => 2,         // Pass a user_id or a list (comma-separated or array) of user_ids to exclude these users

    \'user_id\'         => $user_id,      // Pass a user_id to only show friends of this user
    \'search_terms\'    => $search_terms, // Pass search_terms to filter users by their profile data

    \'meta_key\'        => false,         // Only return users with this usermeta
    \'meta_value\'      => false,         // Only return users where the usermeta value matches. Requires meta_key

    \'populate_extras\' => true           // Fetch usermeta? Friend count, last active etc.
);

<?php
add_action(\'bp_ajax_querystring\',\'bpdev_exclude_users\',20,2);
function bpdev_exclude_users($qs=false,$object=false){
    //list of users to exclude

    $excluded_user=join(\',\',bpdev_get_administrator_user_ids());//comma separated ids of users whom you want to exclude

    if($object!=\'members\')//hide for members only
        return $qs;

    $args=wp_parse_args($qs);

    //check if we are searching for friends list etc?, do not exclude in this case
    if(!empty($args[\'user_id\']))
        return $qs;

    if(!empty($args[\'exclude\']))
        $args[\'exclude\']=$args[\'exclude\'].\',\'.$excluded_user;
    else 
        $args[\'exclude\']=$excluded_user;

    $qs=build_query($args);


   return $qs;

}

function bpdev_get_administrator_user_ids(){
    $users=array();
    $administrators= get_users( array( \'role\' => \'administrator\' ) );
   if(!empty($administrators)){
       foreach((array)$subscribers as $administrators)
           $users[]=$administrators->ID;

   }
   return $users;
}
?>

我在buddydev上找到了这个简洁的小代码。最初用于隐藏当前用户。但它很容易更改为隐藏管理员；

add_action( \'pre_user_query\', \'devb_exclude_loggedin_user\', 201 );

function devb_exclude_loggedin_user( $query ) {

    //do not hide users inside the admin
    if ( is_admin() && !defined(\'DOING_AJAX\') )
        return;
    $qv = $query->query_vars;

    global $wpdb;
    //hide in my case user_id: 1
    $query->query_where .= $wpdb->prepare(" AND {$wpdb->users}.ID !=%d ", 1);
}
