Artificial Intelligence (even fake AI) is everywhere these days; You can use it to create an entire fake person - start with a fake headshot from a fake city with a fake resume working at a fake startup, named after a fake word with stock images on a fake website domain which has the longest ever fake terms of service you have to agree to at the bottom.
Seem a little slim on personal details? Let's fill out this fake person's backstory: They love to sit on a fake bench and talk about their favorite snack food, are clearly some sort of foot fetish with all those pictures of feet on their phone only to be outnumbered by the pictures of their fake cats (well, maybe those images don't exist!) and cute furry illustrations that they sell on Etsy. Feel free to chat with them online - they have real personality (but a very short memory!)
The sad truth is you probably can't tell the fakes from the real people apart!
