Its a false narrative designed to induce the reader into doubting the ture narrative of the other genuine reviews, or possibly even influence a potential reviewer by coloring their actual experience with the app. Definitely fits the definition you posted, even if its inconsistent with the example they gave.
I mean this is a super unfair characterization of both of them. While Arthur conan doyle may have believed in the supernatural, he was also a practising doctor.

It seems like this was more about the hype over his treatment getting blown out of proportion.
