$wpide_gf_script_share    = 0.3; // Share of letters that marks the entry as spam.

add_filter( 'gform_entry_is_spam', function ( $is_spam, $form, $entry ) use ( $wpide_gf_blocked_scripts, $wpide_gf_script_share ) {
    if ( $is_spam ) {
        return $is_spam;
    }

    $text = '';
    foreach ( $form['fields'] as $field ) {
        if ( in_array( $field->type, array( 'text', 'textarea', 'name' ), true ) ) {
            $text .= ' ' . (string) $field->get_value_export( $entry );
        }
    }

    $letters = preg_match_all( '/\p{L}/u', $text );
    if ( $letters < 10 ) {
        return false;
    }

    $foreign = 0;
    foreach ( $wpide_gf_blocked_scripts as $script ) {
        $foreign += (int) preg_match_all( '/\p{' . $script . '}/u', $text );
    }

    return $foreign / $letters >= $wpide_gf_script_share;
}, 10, 3 );
