When LinkedIn (as well as Facebook and a few other social and professional-flavor social networks) is asking you to give access to your e-mail account (Gmail, Yahoo, ...), -- looks at all addresses you have there (people to whom you sent e-mail messages, and possibly those from whom you received messages, and those in your address book), and sends invitations without your knowledge (to "People You May Know").
The solution is simple: NEVER give access to your email to ANY program or website. You don't let the door-to-door sales people into your house to look in you snail mail and your address book. Why would you trust LinkedIns, Facebooks, etc.?! Some people are just too naive, and that why social engineering works. That's how you get hacked or your identity stolen: by believing everything that's written "on the [restroom] wall"
This morning I also received an "invitation" from LinkedIn on behalf of a certain PDML member. That's an indication that he opened his e-mail to LinkedIn. That had happened to a few other PDML members in the past (with LinkedIn and FB).
John, you can actually use the link at the bottom of that "invitation" message to stop future messages from LinkedIn or FB. That a very rear case when I would consider unsubscribing from the message(s) I didn't subscribe to. But I agree, it is annoying.

I've received multiple invites on multiple occasions to join LinkedIn from multiple list members. I don't think the list members are sending them intentionally, but the SPAM does appear to come from the list members' LinkedIn accounts. Anyone who is a member of LinkedIn, please check your account settings. -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
