I reported this to their support contact, and received the following reply:
QUOTE
Anti-Spam eMail Address are incompatible with our automated eMail
processing because whenever eMail is sent to you, eMail is sent back to US
which requires that we manually prove that we're NOT an automated system by
clicking on a specific word in a picture.
But we *ARE* an automated system . . . just one which you WANT to receive
eMail from, NOT a spamming sender.
For this reason, you must provide your actual eMail address if you wish to
receive our occasional eMail updates and notices. You do have another
"real" address which your ISP gave you, and to which your spam-filtered
eMail is sent.
Lastly, as you already know, you can easily add, remove, or edit your
"custom profile" to specify which sorts of eMail you wish to receive
<http://grc.com/mail.htm>.
Thank you for your cooperation, time and patience.
Sincerely,

Does this seem reasonable to you?
I think it's based on a miconception, since my Spamcop email address *is* my
actual email address. It is not a forwarding address. I pay for the
Spamcop email account, and access it directly from my email client by POP3
or IMAP.
