Creative writing for satire or parody are critical aspects of humanity. It is unfortunate when lives are at stake as a result. But there are so many writings in human history that do this - what is your proposition for those?

Perhaps it is attempts at truth telling that should display the clearest warning, as it is generally better to start with the assumption that anything within the realm of normal media is written with an agenda and is probably not entirely true.
As to what counts as fake activism, the claims that were made in the story by raganwald are things that are easily verified as fiction by merely scratching the surface.
Where Mike Daisey actively promoted his work through a journalistic media outlet and only revealed the fabrications after an investigation to trace the interpreter he used in china, this is a post on a blog where as soon as the author is asked, "Is this real?", they write a disclaimer explaining that it isn't, but was written to illustrate a point.
