In addition to the other answers, I want to add the Streisand Effect, even though it is not a complete answer to your question.
The concept is named for an attempt by singer and actress Barbara Streisand to have an aerial photograph of her property removed from a database being used for erosion research. Prior to this, only the researchers even cared about the database, but after her request was publicized, suddenly everyone wanted to know about it. The photo she wanted removed was instead copied to other places and viewed by many.
The idea is that if information is out there where anyone can get it, people generally tend to ignore it. But as soon as people are made aware that someone wants to hide or suppress the information, they have an instant desire to have that information. The linked Wikipedia article lists several other examples, and also links to the underlying psychological phenomenon.
