A very simple blocklist bot for telegram. It will check if a user is in a blocklist. In case he/she is, they'll be banned from the group (Even if the user never entered before).

1. Create a bot in BotFather in instagram (Say /newbot and follow instructions). Save the access TOKEN it'll provide.
2. In BotFather, set /setprivacy to Disable.
3. Run python run_bot.py [TOKEN].

NOTE: You may need to install python-telegram-bot. e.g.: pip install python-telegram-bot.

1. Stop running the script.
2. Edit the source code and add an entry in the BLOCKLIST.
3. Run the script again.
