Suddenly, it becomes the responsibility of everyone with an email address to opt out, over and over;
The truth behind this, that even opting out makes us targets for more spam, calls into question why we opt in in the first place. Same with Facebook and its nefarious terms & agreements- we sign up for our data to be mined and sold so we can be targeted for ads. At what point would the trade-off be too high a cost that we decide to opt out completely, or never to opt in in the first place?
