I also know people who created accounts from scratch without needing a selfie while connecting exclusively through a VPN. (Only some VPNs, work apparently.)
Supposedly FB uses device ID tracking, so if you're picked for selfie ID on a device and try to create an alt, you'll be selfie-ID'd again.
Using a different browser on desktop solves the problem for desktop but not for mobile.
And so on. Basically it's doable, sometimes. And sometimes it isn't.
