It's quite vague. What do "fully use" and "without penalty" mean? So if you have levels or features to unlock via TapJoy or Leadbolt unlocker, and the user chooses not to unlock those features, does that mean he can't "fully use" an app? I hope not!3. Ad Walls
Forcing the user to click on ads or submit personal information for advertising purposes in order to fully use an app provides a poor user experience and is prohibited. Users must be able to dismiss the ad without penalty.
