The Telegram team cares about the level of security of its network and therefore also monitors the IP addresses of users so that they are of the appropriate category.
You need to connect to Telegram using only
Providers or Residential proxies whose addresses belong to Internet Service Providers. Telegram does not block provider addresses for a long time, which makes it possible to work more discreetly and avoid deleting accounts for no obvious reason.
There are also proxy servers of the Data Center category, which very easily and quickly get into the Telegram ban lists and after that cause the deletion of user accounts even in cases of a simple connection.
The so-called Mobile proxies are also Providers or Residential and therefore they are also recommended for use when working with the Telegram network
