I am flooding comment with my plugin in a reasonable manner:

function log_my_comments($post_id)
{
    $my_comments = get_my_comment_data($post_id);

    foreach($my_comments as $my_comment) {
        wp_insert_comment(
            'comment_post_ID' => $post_id,
            'comment_type' => $my_comment,
            'comment_type' => 'my_comment',
            //...
        );
    } //endforeach
}


add_action( 'save_post', 'log_my_comments', 9 );
add_action( 'new_to_publish', 'log_my_comments', 9 );

It will flood comment not more than 5 in a single transaction. Now when I am using my function for user role 'author' it blocks me with:

You are posting comments too quickly. Slow down.

and makes the post to pending.

I can easily resolve the issue by adding the capability moderate_comments to the user, but it is a core feature, and I do not want to hack the default author role. I just want to resolve the issue in a local scope, and not global.

So I took the easiest way of doing this:

function log_my_comments($post_id)
{
    $my_comments = get_my_comment_data($post_id);

    // Disable comment flooding
    add_filter('comment_flood_filter', '__return_false', 11);

    foreach($my_comments as $my_comment) {
        // wp_insert_comment();
    } // endforeach

    // Enable comment flooding again
    remove_filter('comment_flood_filter', '__return_false');
}

add_action( 'save_post', 'log_my_comments', 9 );
add_action( 'new_to_publish', 'log_my_comments', 9 );

But it actually is not working. I tried with priority 11 and PHP_INT_MAX also. Need your suggestion, how can I deal with this?

Update

Thinking about this, I think I found a way of doing this in a right way. But I'm confused on how to execute the idea.

When registering a custom post type (CPT) we have two declarations like:

'capability_type' => 'mycpt',
'map_meta_cap'    => true,

When adding a user role, we can assign the custom capabilities like below:

$the_user = new WP_User( $user_id );
$capability_type = 'mycpt';
$the_user->add_cap( "read_{$capability_type}" );
$the_user->add_cap( "edit_{$capability_type}" );
// ...

In this way we can assign custom capabilities to the user and they map to the core capabilities (read_post, edit_post etc.) when the map_meta_cap is true (as per my understanding).

I'm thinking of a similar solution where I can give the user a custom permission for my custom comment type (mycomment) which will be mapped to the core capability: moderate_comments like moderate_mycomment.

And if that capability (moderate_mycomment) is mapped properly, WP core won't show the error, as for the user the moderate_comments permission is set.

But how can I do this?

PS. I'm storing comments with a custom comment type. (Reference thread)
