Exclude authors IDs from WP_Query

Question

I am using this code, trying to exclude specific authors from WP_Query, however the author IDs in the array are not being excluded. Any ideas please?

<?php
$args = array(
    'meta_query' => array(
        array('who' => 'authors')
    ),
    array( 'author__not_in' => array(10, 3, 4) )
);
$site_url = get_site_url();
$wp_user_query = new WP_User_Query($args);
$authors = $wp_user_query->get_results();
?>

exclude specific authors from WP_Query

You can do it like so:

$args = array(
    'author__not_in' => array( 10, 3, 4 ),
);
$posts_query = new WP_Query( $args );

But if you meant "from WP_User_Query", then in WP_User_Query, you should use the exclude parameter, and that array('who' => 'authors') shouldn't be in meta_query:

$args = array(
    'exclude' => array( 10, 3, 4 ), // not author__not_in
    'who'     => 'authors',         // not in meta_query
);
$users_query = new WP_User_Query( $args );

For the full list of parameters, refer to WP_User_Query::prepare_query() for WP_User_Query, or WP_Query::parse_query for WP_Query.
