Disable temp mail or disposable email domains to book meetings

[piyushgarg-dev]

Is your proposal related to a problem?

So, I have a book now button on my product website at https://www.teachyst.com/ and I am getting a lot of meet bookings from spam emails and domains such as "[email protected]". This blocks my calendar from genuine customers and also pollutes emails and schedules.

Describe the solution you'd like

1. We can have a constant list of known spam and disposable email to block right away.
2. We can use a service like https://www.zerobounce.net/ to detect what kind of email it is.
3. The best alternative for me would be to add settings like "Booking: Authenticated users only" where the user who is booking the meeting needs to authenticate via Google, Github, Microsoft, etc.
