Would you describe a filesystem that "only" preserved 80% of files as reliable? Reliability is relative, one of the defining features of a newspaper is correctness, so only a small amount of inaccuracy is required to make a newspaper be extremely unreliable. I would describe a 0% accurate newspaper by reading it and using appropriate descriptors. Perhaps it is satirical news, a poem, propaganda, gibberish, or simply a newspaper that is never correct.
