Update: temptation got the better of me and I closed my account.
Anyone have any idea how to stop this? (Besides an email filter?) is this practice even legal?
(Imho. Not a lawyer.)
Nothing before I had an account, and when I signed up I turned off all the spam in the notification settings and don’t get any either.
After numerous emails back and forth they eventually added to their "Do Not Contact" list. No emails since!
Probably I’m overthinking this..
