Last week, LinkedIn agreed to pay $13 million and change some of the site’s features to settle a class action lawsuit filed against it in 2013 alleging that it used the Add Connections feature to access users’ email contacts to send invitations to users’ contacts without their consent.

The allegations of the suit include that LinkedIn accessed and collected email addresses from users’ contacts, then sent out emails that looked like they were from the user to the contacts who were not LinkedIn users to persuade them to sign up to LinkedIn. LinkedIn argued that permission was granted by users when the user signed up for LinkedIn.

In addition to the monetary settlement, LinkedIn has also agreed to enhance the user permission process for the use of contact information, including a new screen that states that LinkedIn will “import your address book” if a user elects to use the service which will “upload detailed information about your contacts to our LinkedIn servers.”

Of course, then LinkedIn will mine that data and use it for its own marketing purposes (a brilliant strategy that is in wide spread use). Do you want LinkedIn to upload your entire address book? And how do your contacts feel about having their complete contact information uploaded to LinkedIn for marketing purposes? When I explain these features to my friends and colleagues, some of them are appalled, but have unwittingly agreed to them because they never read the terms of use and just hit “I agree.” When you agree, you are agreeing to all of that fine print.

I was on Seattle speaking at a cybersecurity conference and I offered to find a restaurant for dinner for my co-panelists. I accessed a popular app on my smartphone to find the hot spots in Seattle. A screen came up that said “oops! Your location services are not on, so go to settings and turn them on to use this app” or something like that. Of course, I never have my location based services on to protect my privacy. I did not want the app to have my exact location for that purpose, so I chose to go to another site that did not require that I tell them exactly where I was at that exact time. I found a great restaurant and we ate well. The point is I had the choice of sharing my data and location and I made it. Be aware of your choice when using apps and use it.

Many apps have the same feature. It is important to read the pop up screens and terms of use so you know how these apps are using your data and you can have the clear choice of how you want your data, including your entire address book used by companies. Don’t just click “I agree.” Know what you are agreeing to before you grant your permission.
