1. Instagram can share information about its users with Facebook, its parent company, as well as outside affiliates and advertisers.
2. You could star in an advertisement — without your knowledge.
A section of the new terms of service, titled “Rights,” notes that Instagram will also be able to use your photographs and identity in advertisements. “You agree that a business or other entity may pay us to display your username, likeness, photos (along with any associated metadata), and/or actions you take, in connection with paid or sponsored content or promotions, without any compensation to you,” the new terms say. This means that photographs uploaded to Instagram could end up in an advertisement on the service or on Facebook. In addition, someone who doesn’t use Instagram could end up in an advertisement if they have their photograph snapped and shared on the service by a friend. Facebook already runs ads that make use of people’s activity on its site.
Marc Rotenberg, executive director of the Electronic Privacy Information Center, an advocacy group in Washington, said that the use of a person’s likeness in ads could run into some state laws protecting people’s privacy.
“Most states have laws that limit the use of a person’s ‘name or likeness’ for commercial purposes without consent,” Mr. Rotenberg said. “The legal purpose is to allow people to obtain the commercial value of their images and endorsements, which is a big issue for celebrities and others, but also a reasonable concern for Facebook users whose images are used by Facebook to encourage friends to buy products and services.”
