A very good example of a Telegram Group management bot which is made by Aryza.
It is basically a modular Telegram Python bot running on python3 with a sqlalchemy, mongo, redis, postgress sql and mysql database and an entirely themed persona to make Aries suitable for Anime and Manga group chats.
The bot also has a jealousy feature which causes others to shitpost about the bot.
Person 1: Hey are there any bots which are very good but are insanely with a lot of features?
Person 2: Ever heard of Aries Robot
Person 1: Ah that bot that's op i will make it as admin and also i hope that bot has a lot features like Natsunagi Nagisa
