Spam is something I am super worried about. Like, I know I can't even be careful and audit every person or company I give my email to. It will inevitably end up on a list and make life hell.
On the whole I have learned to be careful, and I would be very selfish, just set up email for myself. My mother is way to happy to sign up for every goddamn thing. She can keep her Gmail, not like it would benefit her or friends if she migrates.
