The account has been limited/deactivated#
Pyrogram is a framework that interfaces with Telegram; it is at your commands, meaning it only does what you tell it to do, the rest is up to you and Telegram (see Telegram’s ToS).
If you found your account being limited or deactivated, it could be due to suspicious activities or misuses of the API in your use case. See https://core.telegram.org/api/obtaining_api_id#using-the-api-id for more information about API usage rules and account recovery options.
