Disconnect published Muse site from Typekit/Adobe Fonts?

[Moderator moved from Muse to Adobe Fonts.]

Hi all!

FIRST A HORT NOTE:  Yes, despite Nancy's best efforts (which confuses many of us!), I am still knocking out GREAT websites with Muse. No significant issues at all.

QUESTION:

I handed off a site to a client who will host themselves. However, I neglected to set up self-hosted fonts before handing off the files and they are still hitting our Adobe fonts server account to serve their visitors.

This creates a few issues:  

1. They are no longer our active client and thus not paying anything. 

2. That means they don't pay into fees paid to Adobe, or any type designers. 

3. I don't think this free ride is fair to anyone.

4. This likely breaks a number of type licensing agreements, and does so using our account's access to Adobe's type servers. I'm not good with that.

So, how can we - remotely - disconnect that domain's access to our Adobe account?

1. I can hand them an updated file (project and exported site) set up to self-host, but they don't care or want to bother with it. Nor do they want to have to buy the fonts they now get for free.

2. Is there any control on Adobe's site to deny access from specific domains (which were entered into the HTML export/FTP upload dialogs)?

Thanks in advance!
