There's only so much information you can get with hardware though. No doubt the software in tracking fingerprints, and matching similar ones has become very sophisticated. However, I wouldn't be surprised if device fingerprints hasnt increased in diversity much.

On the other hand, maybe they're using a spectre/meltdown attack to get a MAC address or something. In that case, we're fucked.

In 2010, Electronic Frontier Foundation launched a website where visitors can test their browser fingerprint.[14] After collecting a sample of 470161 fingerprints, they measured at least 18.1 bits of entropy possible from browser fingerprinting,[15] but that was before the advancements of canvas fingerprinting, which claims to add another 5.7 bits.

If I'm understanding that correctly, that would give 14.6 million unique fingerprints just based on your browser. That's a lot, but also tiny compared to the billions of Meta users. I'm a little skeptical that they would be able to determine a user is from the EU without using IP or cookies.

Edit: If they block users who's fingerprint matches an EU user, and their IP comes from a known VPN service, then they could likely get pretty good accuracy. I wonder if there are any North Americans getting blocked while using a VPN.

Sounds interesting. Do you have a source, or further reading for any of this?
