<<They're going to study up some on reality shows before they go on one, they would hear of "Joe Schmo," and they'd wonder if something was up.>>
Jane Schmo (Ingrid) said in an interview that the only reality shows she has watched were "The Real World" and "The Bachelorette", and Joe Schmo (Tim) hasn't even mentioned any reality shows he has previously watched.
The first season of "Joe Schmo" peaked at 3 million viewers, which is only about 1/4 of the "Bachelorette" audience. You have to think that the "Joe Schmo 2" producers made absolutely sure that neither Joe nor Jane Schmo had heard of "Joe Schmo" or Spike TV, and because "JS" didn't get huge national ratings, that shouldn't be too hard.
<<I wonder if they also know that Spike TV is hosting it, or how Spike TV would hide that fact?>>
Most reality shows, just like sitcom pilot episodes, are not tied to their eventual network when they are produced. Potential reality shows are filmed and then production companies shop them around to various TV networks. There is no reason for Joe and Jane Schmo to even be told that this particular show will end up airing on Spike TV. The producers could simply say, "Once we're done filming 'Last Chance for Love', we will be meeting with TV executives to try to sell it for future airing."
On top of that, Jane Schmo (Ingrid) probably has never heard of Spike TV because a) she is not in their target demographic (young men) and b) she has spent the past few years traveling the world and reading books about Madeleine Albright in her spare time, not watching wrestling on Spike TV.
