Some years ago, Pussy Riot put out information on how to use Makeup to confound face detection algorithms.

On an unrelated note: This is probably going to be blocked in ML because I used the word "pussy". I wonder why that instance has a problem with me mentioning that word. Could it be perhaps the name of a feminist anarchist group activity resisting domestic Russian oppression? No, I'm sure that's a coincidence.

Edit: Ty to everyone who helped correct my misunderstanding. The feedback has been informative, but I'll leave my comment as-is so people reading have context incase they also have misconceptions.
