It kind of happens by default if your goal is "growth at any cost".

The fake restaurant in their garden shed, which never took customers or delivered any food, climbed up to #1 best restaurant in London (!) in TripAdvisor's rankings, purely on the strength of fake reviews and fake photos (artfully arranged closeups of bleach tablets etc). For kicks and video gold, they did open for their last night, serving 1-pound microwave meals from the supermarket.
