FarmVille, Zygna trick gamers into expensive subscriptions

It sounds like a good deal; take a quick quiz and get some free virtual currency or trade your phone number, trade your phone number for your horoscope or even access to "thousands of TV Shows." These are what many users are finding after clicking the ads in mobile games on the iPhone and Android powered cell phones. But they don't just get their horoscope, they end up with a monthly subscription for between $9.99 and $25.

These types of ads first entered the spotlight last year when it came to light that many Facebook gamers where signing up for similar offers in exchange for game currency for popular games such as FarmVille and others from Zynga. Numerous parties involved vowed to clean up the process and prevent these types of ads from reaching consumers on Facebook, which has just diverted its attention to ad-supported mobile games.
