I just got this note from Google, it appears AdWords Policy now Protects against Reverse Billing Mobile Content. They will no longer enable advertisers to publish offers which do not show the actual pricing clearly.
Google Policy Update:
Dear AdWords Advertiser,
We’re writing to let you know about a change to Google’s advertising policies that may affect your AdWords account.
Beginning in the coming weeks, we are expanding our Mobile Subscription Services policy to no longer accept AdWords ads that promote mobile content that require users to enter personal information if the site does not clearly display pricing. Mobile content includes, but is not limited to, one-off purchases as well as subscriptions.
We will also require that subscription information be clearly displayed if the service is not a one-off purchase. For sites promoting subscription services, both the price and billing interval should be displayed along with a checkbox or other opt-in method. If the user does not opt in, he or she should not be able to proceed.
All of the above should be located in a prominent place on the page on which users enter their personal information and should be easy to find, read and understand.
When we make this change, Google will suspend all ads identified as being in violation of this policy. If your account is affected by this policy change, please make any necessary changes to your site to comply.
We have thought hard about our stance on the advertising of this content and the potential effect that our policy decision could have on AdWords advertisers. However, as a business, Google must make decisions regarding the advertising that we accept. We apologise for the inconvenience that this policy change may cause you.
