Telegram bot of mandatory subscriptions

Telegram bot for mandatory subscriptions.
An essential thing if you are an admin of a Telegram channel or just want to gain more traffic in Telegram.

How it works:

There is a link to the Telegram channel, after a person applies to this Telegram channel, they automatically receive a message from the bot with the condition that they need to subscribe to other Telegram channels. After fulfilling the condition, the bot automatically accepts the person into the main channel. Everything is automated.
