Do you track websites? - by norfauji - on WordPress WooCommerce support

Do you track all the website who install this theme?

I found this in the functions.php:

add_action( 'after_setup_theme', 'et_promo_remove', 11 );
if(!function_exists('et_promo_remove')) {
    function et_promo_remove() {        
        if(!get_option('et_domain_tracked')) {
            $panel_url = 'https://www.8theme.com/panel/add_domain.php';
            $url = urlencode(get_bloginfo('url'));
            $theme = wp_get_theme();
            $theme_name = $theme->get( 'Name' );
            $request = $panel_url.'?domain='.$url.'&theme='.$theme_name;
            file_get_contents($request);
            update_option('et_domain_tracked', 'yes');
        }
