I see that in the production list of 137k domains there is the domains associated with https://simplelogin.io/
and https://anonaddy.com/ which are legitimate aliasing services that help to protect our privacy and security by using unique email for each and every account created online.
It's the same recommendation than using unique password for every account. By the way these services are currently being directly integrated into popular password manager like Bitwarden and 1Password. So in the end, having these domains flagged/banned worldwide will be detrimental to end users.
