QuoteLinkedIn may sometimes pair an advertiser's message with social content from LinkedIn's network in order to make the ad more relevant. When LinkedIn members recommend people and services, follow companies, or take other actions, their name/photo may show up in related ads shown to you. Conversely, when you take these actions on LinkedIn, your name/photo may show up in related ads shown to LinkedIn members. By providing social context, we make it easy for our members to learn about products and services that the LinkedIn network is interacting with.

    LinkedIn may use my name, photo in social advertising.
