"""This is an improved version of get_participants.py
|
|
|
|
Since Telegram will return at most 10.000 users for a single query, this script
|
|
repeats the search using numbers ("0" to "9") and all the available ascii letters ("a" to "z").
|
|
|
|
This can be further improved by also searching for non-ascii characters (e.g.: Japanese script),
|
|
as some user names may not contain ascii letters at all.
