February this year, facebook issued a controversy. One point in terms of Service (TOS), more specifically at the content and share information, be modified without notice to users.
In fact, before to any modification that has brought TOS polemic. TOS on the content and share that information mentions that Facebook reserves the right to use content and information (including images, videos and articles) made by the user for any purpose without needing further permission. Then there was more information. Rights did not apply again if users delete the content and information.
