First of all, to clarify my opinion: I would not actually recommend implementing a dummy, based on the principle you mentioned: We don't fool people, period.
Sorry for not making that clear before.
That said, if I didn't care about not fooling people (and were not making open source software, were anyone could uncover the scam), I might actually recommend it, because how could users tell that it was a dummy? They press a button and at some point, the new network is found. Can they really tell whether it was because they pressed the button or regardless of it? And if they can't tell it's fake, it can make them feel
better, and often in the UX business, this is all that counts.
