By what principle are they banned for sending spam vkontakte?

Question

CMS

1) Can someone describe in detail by what criteria a VK page is banned for sending messages?
For example, for the fact that all messages contain the word "hello". Something like this. It is desirable to paint in as much detail as possible.
I know that for sending 20 messages to "NOT friends" and trying to add a friend a certain number of times, they forbid further writing messages or offer a captcha.
Tried to send 20 different messages, but still get banned. Maybe because they contained repeating elements (sentences, phrases)?
Are spam bots tracking spam?

Answer 1

If you are trying to write a spam bot, then my advice to you is to kill it. You will puff for a week on a cool algorithm for changing messages, and then the VK team will tweak the spam detector in 1 hour and you will again sit for a week.

Answer 2

A full ban comes when your posts get a critical mass of spam button clicks from other users.

Answer 4

there is a binary system of numbers. that is, if it has already happened once somewhere, the second time the mention is already spam, and the third and fifth is a ban.
