Sometimes what were essentially private diaries like Anne Frank's and Samuel Pepys get published. Is it possible to make sure that you never become famous after death (& in the future) and prevent such things (diaries, photographs) ever getting published. Can you put clauses in wills or can your beneficiaries do what they want? And/or in hundred years, if somebody unrelated just discovers your private thoughts and/or works (diaries or perhaps creative works you've worked on), can they do what they want with it anyway?
(I'm in the UK, but it may be different in other countries - still somewhat interested in what happens there too)
