Reports--unsubscribes & spam reports

I can't find anything in CC's documentation that tells whether the count of unsubscribers on a campaign report includes any spam reports that may be listed there, or if those two numbers are separate. Rarely we get a random spam report from someone who doesn't like what we are saying in our email, and I understand those are anonymous and Constant Contact can't report who they are from. But the question is, if a report has 2 unsubscribes and 1 spam report, is that a TOTAL of 2 unsubscribes? Or is the person reporting the email as spam, who is unsubscribed by Constant COntact, a separate "unsubscribe" ofr a total of 3. And...does it make a difference if that person both unsubscribes using the unsub link and also clicks to report as spam (in which case would they be included in both lists? Thanks to anyone who knows how this works.
