this is what is new from what iv seen
Facebook | Advertising Guidelines
there is this as well
Facebook Flyers Terms of Service (Flyers Pro)
I agree to the Facebook
Terms of Use posted on facebook.com (the "Site"), as they may be revised by Facebook from time to time. With respect to the content of my Flyers (including any links or images posted in connection with my Flyers), I acknowledge that such content shall be considered "User Content" as defined in the
Terms of Use. I understand that as a visitor to or member of the Site, other provisions of the
Terms of Use, as well as any other agreements I have entered with Facebook, will continue to apply. In addition, I agree that my Flyers will comply with the
Facebook Advertising Guidelines, as they may be revised by Facebook from time to time.
I understand that my Flyers will be run in rotation with other ads, and that Facebook may cancel the Flyers program (including my Flyers that have yet to be displayed) at any time in its sole discretion. I agree to be solely responsible for the content of my Flyers and to comply with all applicable laws in connection with my participation in the Facebook Flyer program. I give Facebook the right to stop posting my Flyers at any time should they be offensive or inappropriate, or for any other reason. I understand that if my Flyer stops running for being offensive or inappropriate, or for violating applicable terms or guidelines, I will not receive a refund.
When I submit an order for Facebook Flyers priced on a cost-per-click basis ("Flyers Pro"), I understand that the particular pages on which my Flyers are shown and the number of my Flyers shown will vary depending on the dollar amount per actual click on my Flyer that I have specified I am willing to pay, the number of page views available to display my Flyers, and the network, targeted audience, timing and other preferences I have specified. I understand that my Flyers Pro may be shown infrequently or never at all if I specify a dollar amount per click that is too low relative to the amounts that others have indicated they are willing to pay, or due to a lack of page views available for my Flyer, based on my indicated preferences, or other limitations. The purchase amount for Flyers Pro will be the cost for each click on my Flyer, which may vary with each click depending on the amounts that others have indicated they are willing to pay for clicks on their Flyers. I understand that the actual cost for some or all clicks may be less than the maximum dollar amount per click I have specified, because the actual cost is affected by the maximum amount others have specified for similar placement. I authorize Facebook, or its designated payment processor, to charge the payment account I specify for the purchase amount of Flyers Pro based on the number of clicks during the relevant time period, up to my specified budget. Generally, Facebook will charge my account one or more times per day based on the number of clicks per day, but I agree that Facebook may wait to charge my payment account until the amount due to Facebook reaches a minimum established by Facebook, the program has ended, or my budget has been exhausted. If I purchase over $50,000 of Flyers Pro in one order, upon mutual agreement between me and Facebook, payment for that order may be made by check instead of credit card. In that case, payments will be due upon receipt of Facebook's invoice.
