QUOTE: We’re seeing more and more scams on the Android Market. Last week, we wrote about a developer that uses popular app names to trick users into downloading fake ones. Before that, we saw a fake Temple Run app making the rounds on the Android Market. This time, we saw 37 more apps that share a similar behavior as the previously reported ones. These are “fan apps,” which means that these aren’t the real game created by the original developer.
