I'd appreciate if they let me unsubscribe from their damn emails on a catch all account where I get a former employee's emails. They make you log-in to opt out and I'm not about to reset the guy's password in case he still uses linkedin.

They don't make you log in. Use this form [1] and they'll blacklist your email address system-wide [2]. Be sure to include any spelling variations (e.g. an optional dot) that may be in your contacts' address books:

  Please add my email addresses to the Do Not Contact List:
  
  [e-mail]
  [e-mail]
  [e-mail]
  
  Thank you,

I did this in April and haven't since received anything but a confirmation from their customer support.
