How does Yandex find the vk id (clickjacking) recognition script in the closed sections of the site?

Question

Search Engine Optimization

The site uses a vk id recognition script.
It is used only in the closed section of the site, i.e. only for registered users.

<? if( $USER->id > 0 ): ?>
код скрипта
<? endif; ?>

How could Yandex detect it? Is it possible to hide it from the Yandex robot?

Answer 1

I found it through the Yandex browser)) Do not let users with a Yandex browser access the site.
Another option is to keep 2 sites - one with clickjunking - send traffic to it, the other without - catch SEO traffic from it.
