A new or bought account cannot be put to work at once — it gets banned. For several days the warm-up behaves like a real person: reads channels, joins a couple a day, chats with your own other accounts. The more accounts you select together, the livelier the chat between them.
Connect accounts first — then you can warm them up.

The warm-up runs slowly and only during Moscow daytime — on purpose, round-the-clock activity gives away a bot. Do not give warming-up accounts any other work.
