How to force VK to show captcha?

Question

PHP

Good day!
Such a problem:
It is necessary that captcha be displayed in https://vk.com/audio . (It is necessary in order to find out where the data is sent when entering the captcha in this section)
I sent various requests quickly, but the captcha does not want to be displayed.
Under what conditions is captcha displayed in such sections?

Answer 1

Add 30-40 records to your audio, you should ask

Answer 2

log in incorrectly many times and you will get a captcha

Answer 3

Unlink the page from the phone number, after linking it to the mail.
When sending a message or adding a friend, a captcha will fly out.

Answer 4

To refresh the memory of the language, standard tricks and standard pitfalls - Stroustrup's book "The C ++ Programming Language", a little more interesting and deep: Alexandrescu - "Modern Design in C ++", if you want to try to understand how the language has come to this: The Design and Evolution of C++ by Stroustrup.
