Did LinkedIn tell you that they recently changed their privacy policy and now allow themselves to use your name and photo for commercial use? they could therefore appear in an advert of LinkedIn without your explicit prior consent.
To check what has been turned « on » by default and eventually turn it off:
- Take your cursor to the right top of the page where your name is displayed and a small pop-up menu will appear. Click on “settings”
- Click on “Account” (left bottom of the page)
- Click on « Manage Social Advertising »
- Uncheck « LinkedIn may use my name & photo in social advertising »
- And save your settings!
Feel free to inform other LinkedIn users you know.
