Facebook's top security officer says that it's really hard to keep bad guys off their site. Testifying before Congress, he said that buying so-called dark ads is hard to stop. Leo says that's because they're willing to pay for it. Leo adds that Facebook really needs to do eliminate dark ads completely and have every ad be seen in the light of day so we know who's buying the ads. But Facebook doesn't want to do that.
