Same. If I subscribed to it (rare), I'll unsubscribe. If I get unsolicited mail of any kind, I'm not "unsubscribing", I'm nuking from orbit by any means available, including reporting to hosting providers. (This has, on occasion, resulted in the termination of a spammer's account, but the success rate is low.)
I'm mostly talking about those emails with helpful hints and upsells that you get when signing up for a new service. People who make a living from spamming^H^H^Hbulk sending may consider those legitimate.
