You could bypass it with javascript adding a script only for logged in users with contributor role removing comment rows with unapproved class from dom.
check if user is logged and is contributor:
if( is_user_logged_in() && current_user_can('contributor')) {
then add a script inline or enqueue a js file with the follwing code:
$('#the-comment-list tr.unapproved').remove();
check if the comments are visible in any other views and add the corresponding classes to the script to remove them form everywhere
/* edit */
vanilla js script:
var elem = document.getElementById("the-comment-list");
for (var i = 0; i < elem.childNodes.length; i++) {
if (/\bunapproved/.test(elem.childNodes[i].className)) {
elem.childNodes[i].parentNode.removeChild(elem.childNodes[i]);
}
}
Modify the comments query
Here's one suggestion, to adjust the comment status for the get_comments() input arguments, with help of the pre_get_comments action:
add_action( 'pre_get_comments', function( \WP_Comment_Query $query )
{
// Only target edit-comments.php
if( ! did_action( 'load-edit-comments.php' ) )
return;
// Only target users that can't publish posts
if( current_user_can( 'publish_posts' ) )
return;
// Halt the query for pending comments
if( 'hold' === $query->query_vars['status'] )
$query->query_vars['status'] = 'non-existent';
// Remove pending comments from the 'all' or '' status view
if( in_array( $query->query_vars['status'], [ 'all', '' ], true ) )
$query->query_vars['status'] = 'approve';
} );
where we target only the edit-comments.php page and modify the status to approve if it's empty or 'all' for users that can't publish posts.
Here we assign the comment status to a non existent status to remove the list of pending comments.
It can be a little confusing all the various status values for pending comments, e.g.
hold, pending, moderated, '0'
depending if it's a label, a comment query variable or how it's stored in the database,
Modify the comments counts
All comments count here:
means the sum of the Approved + Pending comments counts.
When we change the comment query, like above, these comment status counts will not change. We might want to adjust that too.
Here's an example how we can adjust the comments counts via the wp_count_comments filter:
add_filter( 'wp_count_comments', 'wpse_count_comments', 10, 2 );
function wpse_count_comments( $counts, $post_id )
{
// Only target the backend
if( ! is_admin() )
return $counts;
// Only target users that can't publish posts
if( current_user_can( 'publish_posts' ) )
return $counts;
// Avoid infinite loop before calling wp_count_comments()
remove_filter( current_filter(), __FUNCTION__ );
$counts = wp_count_comments( $counts, $post_id );
add_filter( current_filter(), __FUNCTION__, 10, 2 );
// Subract 'moderated' count from 'all' count
$counts->all = $counts->all - $counts->moderated;
// Set 'moderated' count to zero
$counts->moderated = 0;
return $counts;
}
This will also remove the counting number, for users that can't publish posts, from the admin menu here:
Modify the comment status links
Finally we might want to remove the status link for pending comments, for users that can't publish posts:
add_filter( 'comment_status_links', function( $status )
{
if( ! current_user_can( 'publish_posts' ) )
unset( $status['moderated'] );
return $status;
} );
So it will become:
Hope it helps!
I have found this semi-solution, this code hide comment from comment moderation list, but it remove all comment also moderated comment, its ok for now =)

function filter_comments_by_contributor( $all_comments ) {
// get the current logged in user
$current_user = wp_get_current_user();
if ( 0 == $current_user->ID ) {
// Not logged in.
return $all_comments;
} else {
// Logged in.
// check if the logged-in user is a contributor
if ( in_array( 'contributor', (array) $current_user->roles ) ) {
// check if the user is on wp-admin backend,
$screen = get_current_screen();
if ( ! empty( $screen ) && 'edit-comments' == $screen->id ) {
// get all posts by that contributor
$args = array(
'author' => $current_user->ID,
'posts_per_page' => - 1,
'fields' => 'ids'
);
$contributor_posts = get_posts( $args );
// unset the comments given on posts other than his/her.
foreach ( $all_comments as $key => $value ) {
if ( ! in_array( $value->comment_post_ID, $contributor_posts ) ) {
unset( $all_comments[ $key ] );
}
}
}
return $all_comments;
} else {
return $all_comments;
}
}
}
if( is_user_logged_in() && !current_user_can('manage_options')) {
add_filter( 'the_comments', 'filter_comment_by_contributor' );
}
I recommend you to use user role editor to have a full control on users roles in general and add some exceptions to specific users.
