Frauds depend on a stable sense of authorship.
cf. Alan Sokal's fake essay in Social Text--motive of exposing intellectual fraud
A hostile or retributive fraud is a hoax with a trap.
Kent Johnson's fraud in the creation of Yasusada, with the supposed Hiroshima survivor publishing poems in Conjunctions, Grand Street, American Poetry Review, raised questions about poetry--do we value it for cultural information instead of aesthetics, etc.? Authenticity of author's identity eclipsing the aesthetic quality of the work. Johnson acts as the police, bringing out the crimes of American editors in their sentimentality toward victims, prioritisation of authentic voice over aesthetics, etc.
Yasusada's Double Flowering as retributive hoax--cf. responses by Forrest Gander (in The Nation) Eliot Weinberger, Charles Simic. The effect of Johnson's hoax depends on his being a white male. Who speaks in a text is always important; we need to know the historical social space in which a poem exists and participates.
Nasdijj--false memoir of Native American life; significance of the fraud addressed in Time by Sherman Alexie.
The fraudsters want their work to be seen as more authentic than that which they are faking. Resentment toward feminism, gays, other races as arbiters of taste.
The ironising of what is being mocked may then increase its aesthetic emphasis in a way that paradoxically shows its possibility.
