After subscription for the free CC certification, they spam you many times a week, no "unsubscribe" link appears in their emails, the customer support can't do anything about that, postpone my account deletion again and again. Maybe it's legal in USA but in Europe we have the GDPR, so this behavior is by definition illegal
