I'm surprised to read in this thread that the terms of service for AOL's feedback loop forbid us from using its reports to identify users.
The page where you sign up for the FBL seems to say just the opposite (end of third paragraph):
"We suggest using opaque identifiers for the email recipient or a custom remove link in the body of the email to help you identify the original recipient of the message."
