BOSTON -- The man who created some of the most popular social networking games on Facebook is admitting he "did every horrible thing in the book just to get revenues," according to Consumerist.com.

In Zynga CEO Mark Pincus' games like Mafia Wars, Farmville, YoVille and Vampires Live, players compete missions to get to a higher level in the game. The games offer players the chance to buy in-game boosts.

Players can also complete surveys that require "page after page of questions and opt in and out of receiving various kinds of spam," Consumerist.com reported.

Some of the spam ends up as malware and adware installed on your computer that can be impossible to remove. Others leave players with a monthly $9.99 credit card charge that they may not even be aware they subscribed to.

During a speech Pincus gave to some other software developers he said, "I mean, we gave our users poker chips if they downloaded this zwinky toolbar which was like, 'I don't know. I downloaded it once and couldn't get rid of it.' We did anything possible just to just get revenues."

After an investigation, Pincus agreed to remove "scammy offers."
