If it's a complete piece of shit, why do you want to prevent it from being deleted?

In my case, I've maintained old email addresses when:

1) A website ties accounts to email addresses and doesn't allow changing them, and

2) the email provider recycles expired addresses, i.e. a new user could sign up for my old address.

For historical reasons, in case there were ever some account on some rarely used service where I forgot to change the email, and in case I ever need to build something on the MS Graph API.
