Any email that violates the CAN-SPAM act - as LinkedIn's messaging does - I mark as spam. When I can unsubscribe from their emails with one click and no login-wall as they're legally required to allow, I will stop doing this.
I'm sorry if it hurts your experience, but they absolutely deserved to be punished for their flagrant disregard of the law. When they realize that their abusive email tactics actually hurt their users, maybe they'll stop - and then we'll all be better off.
