AFAIK, FlyerTalk isn’t the one placing adverts, but rather the parties paying for advertising rights. I’m guessing there are limitations, and I’m guessing the advertising companies may be less assiduous in what they place than Internet Brands might be in ad selectivity. But we can report ads that go too far and IB can then act and intervene with the advertisement placement companies.
