It probably means you're using your real name and/or your real phone number. Or have an established account with photos of you.
I did not check if images from thispersondoesnotexist.com would work to pass the selfie check, but my guess is that they wouldn't. A professional portrait of someone from a Western country who has never been seen on any photos Facebook owns, not even in the background? That's a red flag. Also, my guess is that Facebook knows about that page and takes precautions.
Anyway, if Facebook tries that hard to make sure I'm not there, why should I join?
