Facebook Can Use Your Content for Promotional Purposes
By posting User Content to any part of the Site, you automatically grant . . . to the Company an irrevocable, perpetual, non-exclusive, transferable, fully paid, worldwide license (with the right to sublicense) to use, copy, publicly perform, publicly display, reformat, translate, excerpt (in whole or in part) and distribute such User Content for any purpose, commercial, advertising, or otherwise, on or in connection with the Site or the promotion thereof, to prepare derivative works of, or incorporate into other works, such User Content, and to grant and authorize sublicenses of the foregoing.
Fortunately, the license expires when you remove your Content from the site. But you may want to pause before you post any of your great photos that Facebook can use for promotional purposes.Lynda.com, in the Lynda.com Article Center, and on Twitter!
