A note that's going around LinkedIn circles reads: "I received the following message from a contact and I am posting it for your awareness and consideration. Without attracting too much publicity, LinkedIn has updated their privacy conditions. Without any action from your side, LinkedIn is now permitted to use you name and picture in any of their advertisements."
That's sort of true. Actually LinkedIn has long claimed the right to use your name and picture in advertisements.
In fact, there's really nothing new here at all. LinkedIn first used public network information in ads in the summer of 2011. After a test run, the popular social network stopped using photos, and came up with its current policy.
But, as LinkedIn also says, "You can control whether LinkedIn uses your name and picture in social ads." Here's how you do that:
Place the cursor on your name at the top right corner of the screen. From the small pull down menu that appears, select "settings"
Then click "Account" on the left/bottom
In the column next to Account, select the option "Manage Social Advertising"
Un-tick the box "LinkedIn may use my name and photo in social advertising"
Personally, I like that LinkedIn makes it so straightforward to control how the company uses my information. Facebook, in particular, is always changing its privacy settings and makes it difficult to control who can see what. LinkedIn makes it simple... just so long as you knew in the first place that your information could be used in advertising without your express permission.
