We’ve all been there: somebody you knew like eight years ago joins LinkedIn, and the site asks you to go add them as a contact. You ignore the e-mail, because hey, you don’t even remember Bob that well, but LinkedIn doesn’t let it go. It asks you again and again to go add Bob to your network. And by the third message you might well be thinking, “Bob! Stop it! I never want to hear from you again! Go away!” Well, now Bob — and all the real, actual people just like him — can sue LinkedIn about that, a court has ruled.
