Every few months, I notice that a new wave of user posted notifications appear on various social networks. These notices primarily appear on FaceBook, and generally attempt to unilaterally limit the sites right to utilize user posted material (any intellectual property, such as pictures, documents, other copyrighted material, etc.).  With specific regard to FaceBook, although they are not alone, it must be remembered that upon establishing an account, the user / account holder, has provided FaceBook with the following: “you grant us a non-exclusive, transferable, sub-licensable, royalty-free, worldwide license to use any IP content that you post on or in connection with Facebook.”. An ex post facto declaration, does nothing to alter this agreement. I was prompted to point this out on FaceBook recently, after I saw quite a few people post a notice declaring their uploaded IP could not be utilized by FaceBook. It is good to remember, that such a declaration is legally ineffective.
