Is Iapetus artificial?

[DethKnight]

 I dont care if it's a natural phenomenon or an artificial construct, what distrbs me is the part where
apparently, according to hoagland, nobody can confirm nor deny radar scanning of object.
 I once worked for the us gov't , and not confirming or denying leads me to infer "plausible deniability" which makes me nervous.
