It is censorship though. Part of the job of the censor is to determine whether the likelyhood some information will be seen, justifies the censorship in question. You can read the censor reports from the estado novo for example, and in many of them the censor declined to ban the book because even though it was objectively illegal, it would naturally be a book that wouldn't be sought after by the general public, and so only those who knew about it would look for it. I'd say this is an even more pernicious form of censorship because you dont know what you dont know.
