Just a short time ago I heard a couple of interviews with people who worked in Spanish radio stations during the Franco dictatorship. They described all the inane rules they had to follow to appease the censors: songs that contained any hint of sex, atheism, "un-spanishness", etc. could not be broadcasted. But none of them knew exactly which the forbidden words were; the censors seemed to make up the rules as they went along. A given song could be allowed by one censor, and forbidden by the next. If the "transgression" was too serious, you lost your job (or more).

All this was, of course, entirely lawful.

Their stories reminded me a little bit too much of recent events.
