A chain letter has been circulating claiming that WhatsApp will be shut down on January 28th. It claims that users will be charged $25 each month to reactivate their account if they want to re-activate their account. The hoax is similar to similar hoaxes that have spread on other social networks such as Facebook. The intention of chain letters like this is to give whoever started it the cheap thrill of seeing it spread between as many people as possible, rather than to gain any financial benefit.”]
