FB's policy on this is patchy. I've known people who have had accounts for years, who were suddenly asked to provide a selfie - often after posting political content. Their accounts were then either locked down permanently, or unlocked.

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.

Seems fairly robust. So why is spam and misinformation so incredibly rampant still?
