Suppose, you make a nice looking landing page. No offers on it, no links to offers or CPA content. You put it on FB ads. FB approves it and your campaign starts. The landing page is, let's say, incent email sign ups. So even if FB ads reviewers tries to do a sign up to check, all is good as they see a thank you message after clicking sign up. Then once the ads campaign is approved, you edit your landing page and put a sneaky CPA offer redirect link to the sign up button so whenever a visitors come, enter email and hit sign up, they get redirected to your niche related CPA offer. How hard and risky is it to be sneaky with FB ads in the above scenario? What are the chances of getting caught and getting your account banned? Unless visitors complains to FB or there is a random review of the ad again, I don't think FB will know that I edited the page. What are your opinions, FB ads experts?
