Radio adverts that use a cell phone ring as a visual cue. There was one for the Dolph de Roos real estate scam earlier this year and now the current one is for the John Commuta “transform your debt into wealth” scam. Apparently the thinking is that the people that are dumb enough to be tricked into calling because they hear a cell phone ring are exactly the right type of people to be lured into these scams. (“Somebody’s cell phone is ringing; where’s my cell?; there it is; should I call someone?; there’s a helpful voice on the radio offering a number; I might as well dial that number”)
