Our company has a google apps account and recently terminated an employee and got rid of his email account. Now I get all his old email to our catch-all. LinkedIn will not let me unsubscribe from his updates to this email address without logging in - which I obviously can't do nor is it legal to make someone login to unsubscribe. Anyone from LinkedIn please take care of this - I get 5+ emails/day from his updates and groups he was in. This is a violation of CAN-SPAM.
Thanks.

"any electronic mail message the primary purpose of which is the commercial advertisement or promotion of a commercial product or service"
I don't think it violates the law because it's sending you updates to his account (which he has contol over), not adverting for a service or product.
