Python script that can connect with multiple accounts via Telegram API, can scrape members from public groups and send messages via username to the scraped members. To be able to connect only via phone numbers or send messages also via ID then please contact me on Telegram. You can find the link at the bottom of the README.md file.
tldr: Messages accounts via phone number and API. If you want to add accounts only via phone, then scroll to the end. If you want more free projects like this, then please support me!
Suggestion: It is better to add by ID because if you add by username only users having usernames will be added. Moreover, it is slow

Sometimes users may not get added at all, this may be because the account is probably limited or you entered a channel. Try with another account.
