We received more informations on the spam purporting from LinkedIn. It is obvious the emails do not come from LinkedIn. Email sender can easily be spoofed.
From the email headers:

The spam even dares to say:
Stop spamming me!
If you see any mails purporting from LinkedIn, do not click on any of the links. As a matter of fact, make it a habit not to click on any links in emails.
