Telegram username is an important identifier for adding users, finding channels, and performing automated tasks. If there are spelling errors, expired user names, or inconsistent object types in the list, it will directly affect the efficiency of subsequent operations.
It is impossible to quickly determine whether a Telegram username actually exists
Users, bots, groups and channels are mixed in the same list
Incorrect or invalid usernames cause automated tasks to fail frequently
Manually searching @usernames one by one is time-consuming and difficult to process in batches
The username data lacks a status label and cannot be directly used for system docking.
