Block account verification with maskmy.id disposable domain

[ghost]

Provider is https://skiff.com/quick-alias and it's actually subdomains, each user can generate their own subdomain. I tested it, very easy.

The page title of https://skiff.com/quick-alias is "Quick alias burner email address". In the HTML I see

<meta name="description" content="Secure and quick-to-create burner email addresses with Skiff!

There is a browser plugin https://github.com/irazasyed/email-masker to create one email per website, skiff.com's twitter account promoted it, the github repository is tagged as 'burner-email'

You should add:

• maskmy.id because it is there main domain
• anything.maskmy.id because it allows you to create disposable addresses with random subdomains

Abusers can sign up with disposable email to bypass disposable mail block, but this can cause Proton being blocklisted.

So I think it is good idea to use something like this:
https://github.com/micke/valid_email2
https://github.com/7c/fakefilter

To block disposables from signing up
