Think it is a joke? No it is not..
This is the phenomenon where an “app” is created to sell something you do not own. What if you make a reservation at a popular restaurant with no intention of going, but you know there is a show that night. Go on ReservationHop and sell your reservation.
What is you are at a meter in a busy city but before you leave you want to sell you spot. Go to MonkeyParking.
San Francisco has had enough and has issued a cease and desist order MonkeyParking.
