Anonymizing a banned user?

In one of my installs, I have a banned user.

I’m considering anonymizing them, but I’m not sure if this would delete the current email address and effectively unban them?

If so, is there a way to ban them again?



As per this topic anonymising users wiped their dats eg their email address.

You can safely anon a suspended user. It won’t unsuspend them.

Okay. So the email address remains registered and the banned user will not be able to open a new account?
