I don't understand how the laundering part works. There was a similar link posted to an overpriced book on amazon yesterday on HN, which also alluded to money laundering.
So if I understand correctly, the person(s) who want to launder their ill-gotten cash publish an app with an outrageous price, and then by the same app with their ill-gotten money, thereby turning it legitimate (buy way of the app company)?
If yes, then how much money could you possibly launder this way? Won't purchase of the same app a 100 times (if that's even possible) raise suspicion? And even then you've only managed to launder 50 - 100 x 100 = max of 10,000 USD. This is peanuts for the real money launders who would be dealing with millions of $ monthly.
