Minor nitpick: sk8terdude69@yahoo.com might very much be my target demographic. That is definitely a private person and probably a real email. I know quite a few people with such addresses that created them during their teenage years, but keep them around.

As a user, I’d prefer services I use not to share my email with any third party APIs who might do you know what with my contact information.

This looks - from a users perspective - like a terrible security hazard or information leak.
