[Please Read] Does sahifa theme have any option to use license key ?

Does sahifa theme have any option to use license key ? I have a sahifa theme and it's running without any license key. But when I check internal files then I see:----

<?php } //______ function tie_before_admin_pointers_container() { ?> <div id="tie-before-admin-pointers-container"></div> <?php } function tie_sahifa_notice_pointer_print_scripts() { $pointer_content = "<h3>". __( 'Howdy!', 'tie' ) ."</h3>"; $pointer_content .= '<p>As you know <a href="http//tielabs dot com/blog/attention-about-illegalnulled-tielabs-themes/" target="_blank"><strong>Sahifa theme is exclusively available for purchase on ThemeForest only</strong></a> for $59 but, Did you know the purchase you made allows you to use the theme on one domain or project. A single purchase is needed for each site you use the theme on. We appreciate following the <a href="http//themeforestdotnet/licenses/standard/" target="_blank">License terms</a> as it allows us to keep supporting and releasing new updates. <strong>If you are using the theme on a single website only, you can safely dismiss this message.</strong> <br /><a href="https//tielabscom/buy/sahifa-envato-1/" target="_blank" style="margin-top: 5px" class="button button-primary">Buy Another License</a></p>'; ?>

Also checked in Virustotal the result came out clean and no any malware.
Is it risky to use ?

thanks in advance
