It is profoundly ironic that Meta is apparently using cloaking techniques against regulators. Cloaking is a black-hat technique where you show one version of a landing page to the ad review bot (e.g., a blog about health) and a different version to the actual user (e.g., a diet pill scam).
Meta has spent years building AI to detect when affiliates cloak their links. Now, according to this report, Meta is essentially cloaking the ads themselves from journalists and regulators by likely filtering based on user profiling, IP ranges, or behavioral signals. They are using the sophisticated targeting tools intended for advertisers to target the "absence" of scrutiny.
