Building a Jeeves for Telegram Channels

Hello all:
I have been looking at the growing popularity of Telegram and adoption by a lot of users. More importantly the lifeblood of telegrams are their groups called Channels. I am seeing channels ranging from Stock Tips to Crypto currency to movies to science. I am thinking managing such channels should be quite complex and wanted to explore an automated way to manage a channel as a service. The idea is to have a bot that can

Provide Personalized service

• Greeting new users and giving them key information on joining
• Track important digital documents / images and share them with users
• Specific announcements for new joiners

Group management

• Ability to stop someone from spamming the group - allow them to talk only once every X seconds
• When was someone last seen?
• Change channel into broadcast only vs AMA session at specific times
• Allow users to invite others to a closed group
• add automatic answers to frequently asked questions
• Track user reputation based on their activity in channel and ban users with poor repute

Membership Management

• Help you with payment processing and membership management.
• show subscription plans, accept payments (with Stripe, for example),
• provide users with invite links to private channels on payment.
• Send reminders for monthly payments
• kick non-paying users.

Sort of a personal Butler (hence Jeeves) for Telegram. Would this be useful?
