Chris, yes and no.

In my experience, the #$%^& AOL user who didn't know how to unsubscribe reported me seven times, one for each email she received from my list. She started on Sunday evening, and I didn't get the reports until I got into the office Monday mid-day. By then, the damage had been done.

It's too easy to report non-spam using Spamcop, and their "Kill 'em all and let God sort 'em out" attitude is going to get them into legal trouble someday.
