One of the people bidding for some work at the Lair called back and told me they had tried to email me some things, but it wasn’t working. Keep in mind I had hit the “contact by phone” box on their webform, and had most specifically not checked “contact by email.”

So I had them read the error to me. Which they dutifully did, including reading the email address I gave their form:

do-not-email@nowhere.net

Even that didn’t register until I said it back to them. And this is why I don’t trust companies with real email addresses.
