I emailed all the suspended users this afternoon with this message:

We have suspended your Hopkins Weblogs accounts because you're not affiliated with the Johns Hopkins University in Baltimore, Maryland. If this is a mistake, do reply and tell me so I can restore your account.

I thought I'd put all of your addresses in the To: field to show you all how very many of you there are. I'd love to hear about how you all found our service. We haven't even launched yet! :-)

Some of them have emailed me back. After a day or two or something, I'll delete 'em all. “May their data live forever in backups.”
