Hello.
I'm trying to parse the site of the contact, this is the answer -
As I understand it, protection works. How can it be bypassed? In which direction to dig?

Answer 1

so start by analyzing requests to the site,
fake all of them completely and get at least the main page
, then see if cookies are used, if javascript is used, etc.
, there is a lot of obfuscated javascript on the site, sit decrypt.
or use PhantomJS or Selenium technologies that allow you to render javascript and you will get the very html you need
