Protect your appearance from covert modeling

Sunglasses or sun glasses (informally called shades) are a form of protective eyewear designed primarily to prevent bright sunlight and high-energy visible light from damaging or discomforting the eyes. (Wikipedia)

The ESPER LightCage 3D face scanning rig is a modern light stage. Avoid going into one of these and do not agree to anyone capturing your reflectance field

Avoid uploading facial and full body photos and video of yourself to services where they are exposed to the whole Internet.
If you need to upload photos, wear protective accessories in the photos e.g. sunglasses, niqāb or burqa.
Do not agree to have your reflectance captured in a light stage.

Protect your voice from covert modeling

Avoid uploading recordings of your w:human voice to services where they are exposed to the whole Internet.
Consider altering the voice of your recordings if you must upload to the Internet with e.g. a w:voice changer or synthetic voice that does not match any human's voice.
Avoid getting recorded by parties whose identity and reliability you cannot verify.
Ask for voice alteration if getting recorded to something that will be publicly broadcast

Ask your parliamentarian to make covert modeling a crime

Contact your representative and tell them to put this hyper-modern lawlessness to check. Ask them to consider criminalizing covert modeling and at least ask them to talk with colleagues and also publicly about the problems caused by covert modeling.
