I also thought it strange, in spite of the form required to avoid these unwanted emails. This is what I received:

You have received a contact request from a visitor to your storefront:
 
E-mail Address: db-Miller2355@escapedemail.com
First Name: Rob
Last Name: Miller
Company: None
Phone Number: (360)246-5768 x8
Request:

COOL SITE

Thank you,
The Quick Shopping Cart Team

He hit our company web site, too. I don't think he is using a bot, because our site requires that the user type a validation code of characters that are not machine readable. However, the email address he used appears to be bogus, because our system also requires him to open a return email from our registration system and click on a link to "activate" his account, which he never did. I'm glad nobody from our company responded, so he didn't get any individual email addresses out of us. Here is the information he provided:
