There's a couple of great open source projects[1][2][3] that try to keep up-to-date lists of domains that belong to disposable email providers.

I would probably not recommend implementing a whitelist for blocking purposes. But perhaps domains on a whitelist could get a slight scoring bump.

As for abuse, I made myself a tool to give myself quintillions of email addresses (not using plus addressing) on gmail.com

I use this to sign up for a service with a unique email that is basically my junk box, but the email is its own unique entry in my password manager
