The month of October was one of the best for Zynga, the company that created PokerLive software, used for playing Texas Hold’em on Facebook. In addition to poker, Zynga has created numerous other games for Facebook users, including the highly popular Farmville.

Although these are two very different games, one consists of playing poker and the other focuses on managing a farm, Facebook’s gains are created in the same way. Poker users can buy virtual chips after having exhausted their daily and free stock. Farmville users can purchase on Facebook any work equipment which could improve their harvests. Although everything you buy is virtual, users use real money to pay.

Those who prefer not to pay can click on one of the banner ads displayed on the gaming interface and sign up for certain services. In return, the companies publicized give Facebook a certain commission.

Some of the advertised companies have been behaving dishonestly. For example, a company offered money to complete an IQ measuring questionnaire. To receive the results of the survey, the player had to provide their mobile number. With this simple action, and without knowing it, the user subscribed to a $9.99 monthly service. Zynga complied with this fraud, unbeknownst to Facebook.

Mark Pinkus, Zynga’s CEO, has pledged to remove all banners from their games. Meanwhile, Facebook has removed the latest Zynga product, Fishville, which recently launched.
