Social gaming applications in particular are being targeted for permitting certain types of scammy ads, that typically persuade users into contracting for services without disclosing costs up front.
In a social game like virtual farming sim Farmville, for example, users can either spend real money to buy virtual goods, or complete offers and surveys from partner companies in exchange for virtual credits. The trouble is, some of those offers include "opt-out" riders that enroll the user in some sort of paid service or subscription, and require action on the user's part to avoid misleading charges.
MySpace CEO Own Van Natta earlier characterized these "opt-out" type of offers as misleading, and announced a change to the Terms of Use to clarify what's acceptable to both developers and users. Popular social gaming company Zynga also posted a statement stating a commitment to weed out bad and deceptive ads, while stressing that the offers industry is still nascent along with a belief that non-scammy offer ads still hold the promise of value to both user and advertiser.
Today Facebook's announcement represents the elephant in the room addressing the problem of deceptive offer ads, and affirms that the major players are now at the table working on solutions to eradicating this type of scam ad. Their blog post indicates they've already disabled two complete ad networks and addressed ad-related violations in over 100 applications, and plan to take further action to police bad ads in third-party networks and apps.
