How do cheat farms work?

Question

YouTube

I want to make a small experimental "farm" of 10 YouTube bots like those that get likes, views, subscriptions, etc. I figured out a little about the YouTube API and I managed to perform a number of actions only if I confirm the request for one account. And how can I iterate through multiple accounts and perform actions through them sequentially? Somehow these farms work and hardly in a semi-manual mode

Somehow these farms work and hardly in a semi-manual mode

Of course, not in semi-manual, but in manual .
Okay, Google - "China Like Cheat Farms"

PS: There are also click farms:

Answer 2

To do this, you need a browser with multi-accounts (for example, chrome) and a proxy. All accounts require fingerprinting for naturalness.
But usually this is done with the help of a zenopster by bots, the accounts of which are pre-pumped. and then perform targeted actions, for example, putting likes.
