I push for a strong "Zero Burden" policy: I will spend exactly zero seconds of my life trying to unsubscribe from something I did not willingly subscribe to in the first place. Report as Spam directly and let the automatic filtering take care of whatever happens next.
Ideally the "Report as Spam" button would evolve into a "Report as Illicit" system that reports to a third party authority with a punitive capacity (while requiring near-zero effort on my side: burden must be with the sender to prove that I willingly subscribe to their messages).
