There is a fairly recent manga ("Kanojo, okarishimasu.") fictionalising the rental girlfriend version of this business. In a two-page preface to one of the chapters, the author depicts a date that he sent his editor on with a girl rented from a real service for the purpose of "material collection". In the wake of that, the author (@miyajimareiji) and the service in question proceed to exchange a series of Twitter PR backrubs, and notably it turns out that the employees of the company (@aoi_renkano and others) all have meticulously maintained Twitter presences. Based on that, I suspect that (1) the people doing the hiring are pretty good at suspending their disbelief anyway and would rather have more information about the "product" they are getting, and (2) the people who are actually going to be deceived are not even expected to track down a Japanese Twitter account, let alone an article in an English-language newspaper with near-zero name recognition in Japan. Regarding the point about the interviewee supposedly being knowledgeable about what English speakers don't know, have you ever seen raw transcripts of a typical newspaper interview? The interviewer and translator (and there almost certainly was one: the English is far too idiomatic, and the person who ultimately penned the article seems to not even know that Japanese names are given surname-first, given how the article is written as if Yuichi were the surname) probably provided a lot of leading that was ultimately left out, or even added in explanations of their own.
