These people may look familiar. They may look like users you’ve seen on Facebook, Twitter or Tinder, or maybe people whose product reviews you’ve read on Amazon. They look stunningly real at first glance, but they do not exist. They were born from the mind of a computer.

There are now businesses that sell fake people. On the website Generated.Photos, you can buy a "unique, worry-free” fake person for $2.99, or 1,000 people for $1,000. If you just need a couple of fake people, for characters in a video game or to make your company website appear more diverse, you can get their photos free on ThisPersonDoesNotExist.com. Adjust their likeness as needed. Make them old, young or the ethnicity of your choosing. If you want your fake person animated, a company called Rosebud.AI can do that and can even make them talk.

These simulated people are starting to show up around the internet, used as masks by real people with nefarious intent: spies who don an attractive face in an effort to infiltrate the intelligence community; right-wing propagandists who hide behind fake profiles, photo and all; online harassers who troll their targets with a friendly visage.
