Farmville, one of the most popular games on Facebook, is full of scams, along with other popular games like Mafia Wars, TechCrunch blogged over the weekend after a heated exchange at last week's Virtual Goods Summit (video here). The games allegedly use offers like NetFlix subscriptions to trick consumers into paying far more for in-game currency than if they just paid cash. The remedy: "Facebook and MySpace need to create and enforce rules against it so that game developers aren't tempted to get a competitive edge by scamming users." "All third party companies that provide services or games through Facebook and other social networks need to be put under the microscope," says Shooting at Bubbles, while Gawker fears  social networks are basically turning in to just another "snakeoil sales channel preying on in the mold of late-night 1-800 number commercials." But there's hope! Just a couple days after Arrington's post, Zynga, the company that owns FarmVille and Mafia Wars, announced steps to clean up its platforms. Arrington finds this heartening: "There may be hope yet for the Internet."
