I have yet to see that actually work. I still get emails from supposedly legit companies, stuff like, "We know you unsubscribed, but perhaps you'd like to give it another go?" I never got back together with any of my ex girlfriends, I'm not getting back together with any of my ex services.
Really? I've yet to see that. The worst I see is companies like Facebook automatically opting me in to new notifications they create, but they do this maybe twice a year and it takes two minutes to uncheck the boxes in account settings, so not really an issue.
